Im pregnant with #2! What should I know?

I have 3 under 6 and the best advise I can give you is to remember every little thing. Take lots of pictures. My 2 youngest are 14 months apart and they act like twins. The best thing for me was I somehow was able to get everything done by a certain time and have them on a schedule. I am as well on the younger side and my husband is 5 1/2 years older than me. I was 20 when my youngest, Zakary, was born. Best of luck to you and your family! What a great blessing you have! :)
