Vivian will be 8 weeks old this week (!!) and I got to thinking - when do you stop referring to a baby's age in weeks and switch to months? I understand why people refer to babies by weeks, because they can change so drastically from week to week, but when do you stop? I feel like you shouldn't go over the teens in weeks, does that sounds right? But then at that point, it begs the question - when do you stop referring to them by their month age and just say they're one, one and a half or two?
So many questions.
