My boy just slept a whole lot more during a growth spurt. He would eat more then sleep more! Same after his vaccinations, would sleep for really long periods of time!
I gave my little ones mylecon drops for gas and it relieved all the fussiness and helped them sleep!
My daughter was the same way. She would be unhappy for like a week then it would totally go away
Def sounds like gas or colic.
Just came from his pediatrician he said its GROWTH SPURT(where babies do this at 2, 3, 6 weeks and then 3,6 months. Its just temporary behaviour for babies. It lasts until 2-7 days, depends on babies to babies. Has anyone experienced GROWTH SPURT?
Gassy or colic just ask his peditrician my son was the same way he was colic though
My son used to hold his gas and it would turn to lower gas, every morning at around 3am he would wake screaming from the pain. We are in Australia and used gripe water, infacol and moved his legs around in big circles to get him to fart. Another way I found to relieve him was to prop him up a bit when he sleeps and also I laid on my side and draped him over my hip, so he was belly down. Deff get your dr to check because it could be something like collic or reflux.
Good luck
He may have trapped gas but I'd check with a doctor they'd know best what may be wrong and how best to help him
