HI Anna its such a hard time isnt it, so much advice and sometimes its so wrong or can make you feel so guilty.

I understand the feed to sleep thing, it was hard to wean MJ off that, but obviosly there are other things in play.

MJ use to projectile vomit at that age too... are you feeding her to sleep in bed lying down?
If you are try sitting up and see if this helps, MJ didnt stop until she was crawling although it gt better as time went on (not every day )
Also do you burp her after she is asleep? i found that i had to very SLOWLY bring MJ upright when she was asleep to burp her and not have her vomit.

There is nothing wrong with you cuddling your little one to sleep, especially at 6 week old when she is still adjusting to the bi bad world out there.

Follow you gut, its so hard to now whats right
