How do you get a routine with a 2 month old and a 1 and half year old?

It just takes time to get in sync with the two of them. And, just as you get it down, one of them will hit a growth/learning spurt & everything will change again. Be flexible. Don't expect a rigid routine. Go with the flow. This time will pass so quickly, whether you find a routine or not.

I felt the same way when my second child was born, (my older one was 2) it all seemed to fall into place on its own when my youngest was around 6 months.

The first thing you need to do is let your husband know that you have worked all day to, and you need his help when he comes home. Then you need to make sure the kiddies are in bed by eight so the two of you can have time alone. Good communication between the two of you is important and working together with the kids when he comes home is most imparative for you and your well being. Now, you need to figure out when feeding times are for your little one, and that is when you will do most of your lovy dovy with your youngest, and as she gets a little older you will spend even more time. You can also incorporate diaper time with her. You can make time with both of them as well, part of the talking will occurr with the little one. Look it is your baby sis brother and state the name, talk about what she he is wearing and count toes fingers and nose and all other body parts, you can also teach body parts that way. Don't be afraid to put the baby down and let the baby lay for an hour or so, just put the baby where you and older brother can be seen and heard. Clean house while everyone is having nap time, and do snacks together. That is all I really have to offer. It is hard to just write out a schedule, because at this age they are unpredictable.
