I've got a nearly 4 year old and 14 month old. Both girls. Having daughters, I've already had to have more than my share of playing Barbies, wearing tiaras, pink, and GLITTER! So there's that, if your baby is a girl. I'll add to the chorus of being there for momma. The childbearing/childbirth process is a whole lot. Plus, if she's nursing, that's a whole other story. For our first, our daughter didn't want to nurse, so I would take most of the overnight feedings. With our second, she only nursed, so I had to find other things to do to help and care for her. Take lots of pictures, enjoy, and it's an absolute blur. I look back and wonder how it happened that my first is already nearly 4! As your child grows, set boundaries and stick to them. That's been tough for us lately, as our oldest fights cleaning up, going to bed, anything. And of course, being a girl, plenty of tears are involved! But, in the long run, being mean and telling them no is NOT being mean. It's being a responsible parent. Enjoy it!!
