So I have tried my lo on a DB bottle instead of Mam. She rejected the teat completely and pushed it out of her mouth so I've put the Mam teat on the DB bottle. She's taken it. Normally it's difficult to get the burps out of her but she is burping quite a lot and they're coming up easily. Do we think this is a good thing or could it mean she's actually taken in a lot more air? Answers on a postcard please!
