Crib vs. Bed

My two year old daughter is still in a crib and we've been debating on the right time to switch her over to a "big girl" bed. We want to move her straight to a twin so we don't have to mess with the whole toddler bed thing. Her pediatrician has told me to keep her in the crib for as long as possible unless she is climbing out which she doesn't. I also have a toddler rail for the front of her crib that we can use to transition her to a bed. Does anyone have any thoughts on when we should move her?

Waaaay too early.

So my precious little boy (15 months old) is progressively waking up earlier and earlier each morning. Today was 6:20 a.m.! NOT OKAY, is what I say! What happened to 7:45 a.m., sometimes 8:00 a.m.? So I ask myself, is he teething? Is he getting sick? Dunno. All I know is that this has been going on for the past week, and I'm bound and determined to stop it before it gets any worse. I run every other morning, and if he wakes up any earlier I won't be able to go running any more! I left him crying in his crib this morning, in hopes he'd just go back to sleep, as I slipped out to get a run in, but came home to my poor husband up with BOTH kids (the crying had woken up my 3 1/2 year old) on the couch.

Help!!
