My 4 week old EBF baby can be a little windy/grumbly (often at night as she can have grouchy, fussy moments then - needing to re latch or spluttering as if too much gas hone down - though shes fine in the day). Pretty sure its not reflux or anything worse than trapped wind as she doesnt cry or vomit, just grumbles, lifts legs etc and it improves with winding.
Some other mums mentioned gripe water and infacol.
Daft question but what are they? How do they work? Do they work or am I better off just patting her back for ages at 1am.
