Hello, well this sounds like fun!I bet you're dreading every feed! I hope these suggestions help: put in 5oz and see if she takes it-dont worry if she doesnt.Play with her,take her out ,anything to distract her before the next feed-which should at this stage be every four hours.Make another 5oz bottle and see if she takes it all-because she should be hungry enough.If she doesnt dont stress,do the same distraction thing untill the next feed.Basically you need to see if she can adapt to a routine,and that way you can get her to regularly take the same amount and youll know when she is ready to go up to 6oz bottles.It also doesnt help if she can sense you getting upset, so try and think she's not going to go hungry,youre not doing anything wrong,youre just trying to see how much milk she needs.It might be an idea to get your health visitor to see if she needs to be fed in a different position or maybe shes got wind from the last feed and cant take more milk,or maybe she needs a different teat on her bottle.She might even be coming down with something,or starting to get sore gums ready for teething.Dont worry about her weight, it will take off eventually.I hope things get better soon,but dont worry
