We have the Avent bottles and have tried the teats with 2,3 and 4 holes in, the 2 hole teat seams to make him more sleepy and the 4 hole seams too fast, and at the mo we are using the 3 hole. I have also tried the vari flow but he wouldnt have them at all and ended up having to change the teat mid feed. Its good to know that we are not the only ones in the same boat, im not getting much off the health visitor on this apart from the teat change and bongela incase he is teathing which we have tried. We had lots of scans and monitoring because they said he wasnt the correct size for dates so i was induced just under a week early because of this. They think it was the placenta. We are constantly worried cause of this and wonder if hes doing what he 'should be' they dont tell you when you should be worried just they will keep an eye on him. Hes only just started to hold his head now, still a bit floppy but much better. Ive never been so worried in all my life and im quiet a laid back person. Kids eh.
