Does anyone have any good tips for winding after a feed? Dexter (bottle fed) has a couple of good burps with back patting & rubbing but i'm scared to put him down for ages in case he brings more up - at night he often sleeps on daddy's chest so he's facing the right way if anything did come up. i'd like to be able to put him down in the basket soon after a feed but he seems to get wind up to an hour or two later....
