11 weeks, throwing up a lot of feed, very grizzly

[Huntersmum15]

Abit of mothers advice please.

DS turns 12 weeks on Friday. However he seems to be the most miserable baby, he's always winging or crying. The last 3/4 days he's been throwing up most of his feeds and he seems to be getting gas in his belly so he is constantly raising his knees to his stomach and squirming and then seems to strain when he poo's like he has trapped air. Could this be a sign of colic?

Hello - I posted a similar question about my 7 week old being unsettled during the day in the sleep section (I thought she was over tired and not able to nap because of that) and had some interesting replies regarding reflux. I'm new to this (mumsnet and being a mum!) so not sure how to link my post. The thread was active today so you should find it in the sleep section.
