So I had baby number 2 six days ago. Baby number one is nearly three. I've been so exhausted being up with baby all night I'm falling asleep breastfeeding sitting up! While that is getting a little better, I've got no patience for my daughter. She is constantly fighting me on everything, though she has been fantastic with baby brother. I just can't take it and I feel like I'm constantly snapping at her, which just isn't fair. I was so overwhelmed today I was in tears. I don't know how to handle it as NOT breast feeding isn't really an option , so getting more sleep isn't exactly in the table. Could this be depression or is this normal?
