history: going through my childrens old clothes I went thru my childrens old clothes the other day and its hard to believe they are grown up now. 
current: Oh I understand, mine is only 2 1/2 right now but I feel that way too when going through his preemie clothes. You probably feel it much more if they are grown though.
next: I think we probably feel it about the same! It was a nice memory to come across tho.
