Hi N.,
Sounds like you have a lot on your mind and on your plate. I tend to agree with Christine's response - your family has to come first, especially since you have such a small child, not even a year old yet as you wrote your query. Also, if you think you feel overwhelmed now - I wouldn't even think of adding law school to the mix.
A little about my background (so you see I'm not just talking through my hat!)....I finished my university education as a nontraditional student (1st marriage, no kids then), graduated summa cum laude with a double major in psychology and English/creative writing, and now I am happily remarried and a SAHM with a 2 year old daughter. Prior to my marriage and motherhood, I did have a professional career and enjoyed many aspects of that...but surprisingly I don't miss it like I thought I might. The rewards of family living far outweigh the momentary kudos and satisfactions my job used to provide.
Here are some things to think about...
With a young child, I can't imagine trying to take on something with the depth and intensity that pursuing a law degree would require (I tend to be an intense student in any case :) ). I have a good friend (married, no kids) who went through law school, and from all I know of her experiences, it is MUCH harder than I suspect you may be anticipating - it's truly extremely demanding and will consume your thoughts and life. Practicing law is also a very demanding field (if you want to be successful) so things will only get more stressful, not less, once you have graduated and passed the bar exam. (My friend vouches for this!)
I'm sure you already realize that time you spend in lectures/class is the least of what will be demanded of you as a student, particularly of the law - there will be tons of individual study, writing, research, etc. etc. To succeed as a student you must have the time and energy to think clearly, work hard and be uninterrupted for long stretches of time. Similarly, to do well as a mother, you must have the time and energy to devote to caring for your son during his waking hours, playing with him, reading to him, taking him places, exposing him to new experiences and giving him a safe place with you to explore, test and learn....plus meeting his basic physical needs. In a sense, as mothers we are "students" of our children's needs and changing personalities, as well as being their most important teachers.
The difference between law school and motherhood is that your child's wellbeing and development is dependent on you in a very unique way - no one can replace you and the time is fleeting while he will be young and needy. Your decisions (on this and other things) will fundamentally affect your son's life and future on multiple levels.
You are correct to be concerned that you will have virtually no time with your husband as well, if you choose the law school avenue; naturally this would place a strain on anyone's marriage, even if your h says now that he is supportive of your pursuing this course of action. Taking on tremendous loans is also a black mark against this choice - financial stresses are perhaps the leading cause of serious marital strife. I realize that education is expensive but you can plan ahead and minimize the amount of debt load you incur for your family's future.
It's unclear from your post who will be caring for your son while you take classes, study and do research. He is still very young and small, and at his age it will be extremely unsettling to him for your attention to be so scarce and your focus to be away from him so much - he needs both his father AND you to be his primary caregivers right now. The reality of child development means that this will not change for many years to come.
Since you directly asked for advice :), these are my thoughts: why not simply put law school on the back burner for now? You're 23 years old (still young) and thus could easily wait many years and still be capable of pursuing this dream when your son is much older. Since you were accepted already at a couple of schools, you must have the appropriate background education and abilities, and these attributes won't just disappear. If law school is on your future agenda, you and your h can start saving money toward your education (as well as your child's, don't forget!!) and at least make a dent in the costs so you don't have to hang a huge millstone of debt around your necks for years to come after you complete your schooling.
You chose to marry and have a child, so I know you must value your family - and whether we like to acknowledge it or not, successful marriages and children both require a great deal of attention, effort and nurturing to grow and thrive especially in our stressful world (both your h and you bear this responsibility). Relationships and people can't be put on a back burner, not without risk of great pain and loss.
Getting a law degree is a fine objective, but it's not worth attaining it at the expense of sacrificing the peace, love and harmony in your home and your marriage - and it's ESPECIALLY not worth sacrificing your son's natural needs for his mother's focused and sustained attention and love. You are fortunate in having this choice - I do realize not everyone does; some women are forced to work and leave their children in the care of others for most of their waking hours, which is very sad for everyone concerned, even when it's supposedly the mom's "choice" to be a full time employee rather than a full time mother.
N., our kids are young for such a short time in the grand scheme of things, and IMO we owe them the best emotional life and stability we can manage to provide before they reach adulthood, whatever our situation may be. Our choices shape their future! Being a good mother is a full time career in itself, and the rewards are priceless. When I get discouraged, tired, bored, frustrated or at my wits' end with being "Mama," I always think of that old saying, "When you're on your deathbed, what do you want to look back and see that you've done with your life?" The point being that in the end, loving relationships are what matter forever, not money or recognition or "professional success" in any field. That's why I am so confident in saying, "Wait!" ... as long as you and your h are making a good happy home for your son to grow up in, you are doing what is most important in life.
Remember this final thing, too ... you will change and grow over the next several years as well as will your son, and you may even find that your dreams take a different turning as you move forward through your life. :) Much better to put your time and effort into your son and see what dreams may come with time.
May God give you wisdom and discernment in making your decisions, and shower many blessings on you and your family!
