I remember rough ages, not dates, for DD1. First teeth, 9 months. Can't remember crawling, was quite average I think. Walked 10 months 10 days.
DD2 - No idea on teeth, but earlier than DD1, can't remember crawling - but she didn't do it long or much, we sort of went straight to walking, walking unassisted 9 months.

Beyond that though, not much! LOL Can't remember how old when they first spoke. ExDH thinks their first word was dad, DD1's was actually ice cream randomly at 11 months, then nothing else for several months. But I haven't the foggiest when either rolled either way or sat up or smiled.... I meant to write it down, but just never did.
