Have you thought about asking him why he doesn't want to go to bed?
he's not really talking yet, possible hearing problem... going to get that checked soon.
But i know why he doesn't want to go to sleep
he wants to play, watch tv and run around.
My little guy is starting to say a couple words at once... bed time, My truck, mommy and daddy, car ride, bike ride. fire truck and plenty more. MINE
Make sure you read to him on a regular basis. Couple times a day. Start with little books with tiny sentences.
Is he not in a crib anymore?
