My daughter is 6 weeks and never gets her wind up. I do it properly and will sit there for almost an hour sometimes and she never burps. I've had other people try to do it also and nothing...
I've tried lots of products aswell and I sit her up 30 mins after each feed. Does it matter if they don't burp???? She's never in pain or anything so I know she doesn't have belly ache/ trapped wind she just cries for a bottle
