Hi J.! I think a lot of people are giving some great advice, but someone named Kim K...well, I more than agree with her. It's like she took the words right out of my mouth!
I have a boy and girl who are 20 months apart (Alex just turned 2.5 years, and Anna is 9.5 months old.) I won't lie to you...it is so so so very hard a lot of the time! I don't work, and I think I thought I would be this wonderful supermom who could get everything done, so it was basically a huge shock to my system when I learned NOTHING gets done around here! My house is always a mess, and just when you get the laundry or dishes done, there are suddenly more dirty clothes or dishes piled up. However, my husband works a ton of hours and really is not home to help out hardly ever. Even when he does come home at a decent time, the kids are usually tired and ready for bed, and guess what? When they are tired (or sick) they only want Mommy!! It really is a big juggling act. If your husband is around more and is able to help out, you may not have some of the issues that I have.
And I really do feel guilty at times that I am not giving my kids enough attention, especially the youngest (my little girl.) Maybe it's her personality or maybe it's because she just had to get used to it, but my dd is pretty good at entertaining herself, and while I feel bad that I cannot spend as much one-on-one time with her as I did with my son, she is actually growing up to be one very happy, healthy, active and smart little girl!!
Somebody else (on this board) mentioned that it's hard to take 2 kids out so she stays home a lot. I am pretty much in that boat right now, too. My daughter takes 2 naps (her first one is around 10 am, and the 2nd one is her longer nap, around 2 pm, and that is when my son is sleeping as well.) So it is sort of hard to go somewhere in the morning, but if I really need to go somewhere or if I'm really feeling trapped and we need to get out of the house, I just make sure I do enough driving around so that she gets at least 20 minutes of sleep, which is shorter than her normal 45-60 minute morning nap, but it's enough to hold her over for a while, and then I just put her down a bit sooner for her afternoon nap. It all works out. Also, this weather doesn't make it easy to get outside; sometimes it just seems like so much work to get them all bundled up to run to the store!! And what they say is true: once you get the kids all bundled up, someone always has to poop, it hardly ever fails. But soon it will be warm outside and it is going to be so much easier just to run outside with them, instead of taking 20 minutes just to put their coats/hats/shoes on!!
It can be really tough at times, and even though I've always thought myself as some great child caregiver, I find myself brought to tears every so often because it seems like I can't handle it all! And this is WITH all the help I get from my parents and my in-laws, who are willing to take the kids for the day or overnight, anytime I need them to, just so I can clean my house, run errands, or go out on a date with my husband!
But you know what? I do not regret it for a minute!! It's true: as for baby # 3, we are definitely going to wait a bit longer, at least until BOTH kids are completely potty trained, because I know I won't be able to do this again. But with these two, all the hard times are just temporary! It won't always be this way, and so many people have told me that it gets easier as the kids get older. I'm starting to see that already. My dd is 9.5 months old, and she is actually on mostly table foods already (my son was a bit older before he was handling table foods as well as my daughter is.) So that makes it easier for me to take them out; if I don't feel like bringing along a bottle to the store or wherever, I can now hold her over by bringing a long a sippy cup and some Cheerios or Fruit Puffs.
And my kids love each other so much! My son still gets jealous at times and once in a while, he'll tell his sister to get away from him, but usually, he loves to play with her and helps me "take care of her". As for my daughter, her brother means the world to her, and seeing her constant smile for him just melts my heart. I love these two kids more than anything in the world!
That said, just be prepared. I have heard (and have now witnessed) that having 2 kids so close in age is more like having 3 kids. It really is very tough. Just be prepared. Be prepared that it will be tough, and that your house will almost never be clean, and that you will be physically and mentally exhausted. (I think that was my problem: I wasn't prepared for the daily chaos that is now my life.) But again, all of this is just temporary, and the rewards really do outweigh any of the negative things having 2 kids under 2 can bring. It is AMAZING how your love grows and doubles, and you do not love one child more than the other.
Oh, one more thing, about telling your mom. I told my mom when we thought about having our 2nd one, and yes, she thought I was crazy. (My kids are 20 months apart, but they would have been closer in age, but I did not get my period until my son was 9 months old, and then it took us 3 months of trying to conceive our daughter!) So yah, she told me I was crazy and that she thought it was best how she did it, spacing me and my two sisters 4 years apart each! I just kept telling her that I would be fine, and now, I try not to let on how hard it can be for me, because I don't want her to think she was right! I think she knows its hard on me, but she LOVES LOVES LOVES her grandkids, and I know she wouldn't have it any other way. Besides: this was MY decision, not hers, just like this is YOUR decision, not your mom's.
Good luck to you!!
