Felix has a mild form of reflux which caused lots of problems for us before we figured it out. He was also a big 'sucker' and did lots of mini vomits after a feed...to the point that I thought he wasn't taking anything in (although his weight gains were fine)

Things we did to help...

raised his basinette (and later cot) mattress up so it was on an incline...just put a folded towel underneath where his head would lie

burped him halfway through a feed rather than waiting til the end...especially when he started to fuss at the breast

used a dummy (this apparently helps with reflux)

used a sling (again, keeps bub upright)

started using a reflux medication made by a local pharmacist which contains an anti-spasmodic and an antacid...this has really helped!

If you want the name of the pharmacy, just pm me...

Hope that helps...and your little one settles soon!
