I have been trying to get my 4mth old to feed from a bottle since 6mths without success. The screaming has stopped now but he never gets the hang of it. We have tried every kind of bottle teat and now cup but nothing seems to work. We try one thing only and then a variety, different time of the day but no success. I have completely run out of ideas and feel like I need to stop BF to really solve this. Also going back to work in a couple of months.
