O is 16 weeks now. In the past he has had trouble with trapped wind - even when being fed upright, winding every 1-2oz & keeping him upright for 30 mins after feeding. Fennel tea has helped, a lot. We only have a "blip" once in a blue moon now. Recently, especially over this last week, I'm really struggling to get him to bring up any wind. Tonight, for instance, he had his 6oz bedtime bottle & i got absolutely nothing. I'm now worried he's going to wake in a while in a state. At what point did you all stop winding? Is him not bringing up much wind (if any at all) when being winded a sign that he's sorting it himself?
