I have cut out morning naps completely since if he has a morning nap even for 15-20mins there is no way he will go down at all in the afternoon. He will cry the whole duration of nap time without any give in the crying. I have been going back in every so often to reposition him back down and telling him its nap time. If he doesn't nap in the morning he'll nap but it seems to get shorter and shorter everyday. Parents aren't really concerned with him not napping they say he always naps for them in the vehicle whenever they go anywhere. which makes it hard for us to have outings because he's so in tuned to napping in a moving vehicle or on walks in the stroller.
