This is just what we did -

(1) to let baby sleep with blanket - about six months with it tucked around her sleep positioner
(2) to let baby sleep with pillow - 16 mths : jr pillow
(3) to change crib to toddler bed - 16 mths
(4) to have her feed herself with forks/spoons (not finger food) - she wanted to around 14 mths and is really good at it now
(5) to give her peanut butter - 2 yrs
(6) to potty train - still waiting she's not ready yet at 27 mths
(7) to tell her when we get pg with #2 (no not even ttc yet!!) - we told her straight away and she was 15 months at the time.
