At that age, DS was in the same sleep pattern for the day he is now - short naps only, three times a day! I used to be able to get him to do a longer nap at lunchtime, but he's not wanting to nap for more than an hour now.

I gave up fighting him down in the day. He would sleep in the car, in his pram, after a feed at the appropriate time. So I let him sleep where he was - the bed was nighttime only. Then once he wakes up he comes in with me; quite often my presence will help him re-settle, especially in the small hours when I can just stay asleep myself while I pat him!

HTH.
