Your DS is at that very "windy" age, my DS2 was the same. He would wake up crying and pulling his knees up so we gave him Infacol before every feed and it made a huge difference. There are lots of products that can help with wind. An all natural one is Brauer Colic Relief, you can get it from most chemists. Also Infants Friend or gripe water are meant to be good, I think it all depends what suits your bub.

I've taken both our bubs to paediatric chiros and it made a big difference with both of them. It's definitely worth going!
