Wow born on her due date, congrats and welcome little megan.

I know how you feel about not being able to give enough time to DD1. Having that 2nd child takes a while to adapt to. Going from 2 to 3 is so much easier and after that it just doesn't matter lol. When Megan is sleeping (and your not napping) give DD1 some one on one time then. Read her some stories and try to get some books about babies and being a big sister. I know she is only 2 but they do still understand some of it. My DD2 is 2 and we talk to her about being a big girl helper. Take it day by day and try to relax about things (hard to do I know). Take care
