DS1 will be 2 1/2 years at the end of this month. The first week we brought LO home he did just fine. Then at the start of the second week I feel like we suddenly came into the 'terrible twos'. He won't listen to a thing we say. Everything is no. He seems a bit out of control. Its breaking my heart because I'm sure its a lot of change for him too and of course, as Mommy guilt goes, I just don't feel there is enough of me to go around right now. He has become best friends with Daddy lately - which is good - but still a tough adjustment. How are you trying to get existing children back to 'normal' since the arrival of LO?
