DS is almost 3 weeks old and is EBF. About 3 days ago he started getting really upset after feeds and at random times in the day and night. He screams and cries in pain, arches his back, stiffens his legs and makes a horrible straining sound. He doesn't do many burps but lots of big farts and poos. He is putting on lots of weight and doesn't vomit. For the first two weeks he would feed every 3-4 hours but now this is every 2 hours in the day and more frequently at night...I'm not sure if this is more for comfort rather than genuine hunger.
Sometimes holding him upright after feeds helps, sometimes it doesn't. I have propped his mattress up and try to wind him after feeds.
How do I know if this is normal wind or if it is reflux and needs advice from a doctor? Winding him doesn't really produce anything. He will fart after lots of crying and writhing. Should I try infacol? A dummy?
The constant waking, feeding and screaming at night is already getting me down (also have a toddler to look after). Any advice please? Thank you.
