When people ask me how Isabel is doing with having a new sibling, my response is GREAT, although there are times where she does love him a little too much...for example:
When she kisses him, she kisses really hard and makes him cry.
She also wants him to wake up all the time, so she'll say, "Wake up James, morning James." We've had to teach her that it's okay for James to sleep during the day because he's so little.
My only other concern is that Isabel isn't very aware of her surroundings (kind of like me) she's very klutzy. (i.e. she received her first black eye from running into the dinner table). So...we don't usually leave James on the floor unless we are right next to him, since she has a tendency to trip and fall and I'm thinking James might not be the best thing to fall on...
She loves to hold James.
James likes to chill with me on the floor outside the bathroom while I'm getting ready for the day. Isabel decided that he needed some company.
