I have a 3 1/2 year old boy and a 10 week old baby girl.
I don't have any advice but just wanted to let you know that I have the same problem with my 3 1/2 year old.
As soon as I start to feed Ella or am trying to get her down for a sleep, my son wants a drink or something to eat or to play downstairs.
He is much noisier and active since Ella's birth.
I'm just hoping that things settle down.
