DS is 4.5 months old and lately (well I'd estimate for about a month) has been being sick after all his feeds, sometimes quite a lot. I'm not sure what is normal 'possetting' and what counts as vomiting? And what is a cause for concern?
He doesn't seem too fazed by it but I am sick of being sicked on 
It does coincide with him switching over completely to formula, he didn't spew at all when BFing but I did have supply problems.
DS has been constipated forever, even when BFd, so have been advised to water down his feeds - 5 scoops instead of 6 for a 6 oz feed, for example, however that seems to make him more sick. I've read that for reflux they give a thicker formula, but don't want to do that as worried it will make him more constipated. I don't think he has reflux.
We had a small, firm, green poo this morning :(
Also I feed him after each nap and he absolutely chugs a 5oz or 6oz, but lately his naps have been crap, only half an hour ish, so then he's only awake sort of an hour between naps, so then he's not hungry when he wakes up from a nap. And by the time I feel safe lying him down either on back or tummy after a feed, it's time for a sleep again, so he doesn't get much playtime unless he's sitting up with me. And whenever I put him down anyway he is sick.
He coughs, sneezes, chokes a lot, just for info.
Have bought some variflow teats this week after he was getting distracted with a slow flow but drowned with a medium. He is still flooded with milk and leaking out of his mouth though.
Im happy to carry on as we are if all sounds normal but just wondering if that does all sound fine?
Off to change DS into second outfit and put him down for 2nd nap of the day! Already!
