My 12 week DD is EFF with Dr Browns bottles, level 1 teats and 1 dropper of infacol as she was a colicky / windy baby when younger.
Until 6 days ago she fed well, taking 5 x 6oz over 12 hours and sleeping all night.
I can't think of anything which has been changed but she now feeds for about 5 mins then screams and pushes the teat from her mouth. She continues screaming (v loud, bright red in face, inconsolable) until you stop trying to feed her i.e. lie her down on her mat etc when she immediately starts smiling.
We initially wondered if there was a positional element and she does seem to feed better if a bit more upright but she is not at all distressed when lying down immediately after feeding an dis not a "pukey" baby.
We have tried different bottles and also tried faster teats (both Dr Browns and other bottles) with no benefit.
If we stop trying to feed her for 10 mins then try again she will take a couple more ounces and if we stop for a further 10 mins she may take a third small feed and so manage most of her bottle.
At night she tends to feed "normally".
She doesn't have any obvious teeth coming through.
Any thoughts about why she has suddenly started screaming while feeding and what we could do to get back to undistressed feeding?
