Totally normal. I stayed at home the first year with my first child...My daughter started child care at 5 months. It really all depends on if you can afford to stay at home and if you really want to stay at home or go back to work. I definitely miss my little ones while I'm at work, but bills call!
If you need help in finding day care let me know! My daughter is almost 8 months old and she is with a nice young lady at an in-home day care...
By the way, when searching for the right child care, you have every right to question and drill that day care provider with questions from experience to credentials (certifcations in CPR, registry with the health department) You should never feel inferior to a care provider with whom you do not know.
Take your time to get to know the people and the place you will be leaving your child with. visit often, call often and sometimes take him home early. Especially in the beginning, you don't want to leave him there all day. You and your son, both, have to ease into it.
I use to babysit in the evenings. Had this woman not known me and my family then I'm sure she never would have asked for my services. My husband worked with her and suggested we could all get to know one another...It worked out for a while, but she just couldn't afford me!-not that I was expensive! LOL
