Thank you for the advice - I wind her loads, we do her bottle feeds slowly/responsively so she's not guzzling and she has a slow flow teat bottle.
She is on the ready made formula still but will switch to powder soon, just has been easier since we had to get it in a hurry.
Her poos are yellow/normal looking and very soft so can she still be constipated? She does maybe 2 a day.
She is finally sleeping exhausted on my chest after a horrendous episode of straining, screaming, passing gas, crying, curling her little legs in and then pushing them out again so hard. It went on for about an hour and a half and we tried bathing her, rocking/walking her, feeding her, nothing seemed to even give her much pause for breath. She was hungry so did pause to have her bottle but then started 5 minutes later again and was sick twice.
At one point she seemed to settle but then was sick quite a lot. She has the most terrible hiccups that really seem to distress her and putting her down on her back is almost impossible as the hiccups/sick usually come on immediately.
I hold her upright for half an hour after each feed. I'm just at the end of my tether and want to help my beautiful baby feel better 


I'm waiting on a call from the midwife but really feel spent and like a crap mum.
