DS is 3 months old and exclusively breastfed. For the last week he has been crying inconsolably after feeds, particularly in the afternoons and evenings. This starts about 10-20mins after a feed and lasts until I take him out in the car or buggy or until his bath. He possets a bit of milk but doesn't really vomit and feeds well. Early on we had problems with crying/choking at feeds, probably due to over-supply of milk/fast let down but this settled really well with block feeding. He is thriving with very good weight gain and is otherwise well, although waking frequently at night still. I've always thought he was a bit of a grumpy baby, slower to smile and generally more upset than older DD and up to now I've accepted this as his personality and haven't been concerned. I'm now wondering whether he might have silent reflux and wonder whether I should be trying gaviscon or similar. In general I believe that little babies cry and tend to get better with time and I wonder whether the terms "colic" and "reflux" are over-used sometimes to try to explain the crying. However I don't want my little chap to suffer if there is something I can do to help. Have also wondered whether he is just hungry and needs supplementing with formula but don't really want to do this. Any advice welcome please.
