hi, T.!
great question! my little guy is 28 months now, and right now we couldn't live without our baby bjorn potty trainer (it goes on the big potty and makes it child size)...it makes potty training a lot easier and cleaner too!
i also love our britax car seat and our little tikes racing car big boy bed. For the bed, i love the sheet sets that contain the bottom fitted sheet with a top fitted sheet (fitted on the bottom so it doesn't come off!)--i am not sure what i'd have to do if i had to tuck it in all the time! we are also in love with the book "good night gorilla"--a great read. we love our wooden puzzles, and have recently come to enjoy games! he loves "the bean game" (don't spill the beans), the "ice game" (don't break the ice), and candy land color bingo. at 28 months he knows how to take turns, color and count!
i'd love to read other responses as well!
thanks!
-B.
