DS is 4 weeks and breast fed but have started to offer him bottled if expressed milk in the evenings. We bought the 2 of Tommee Tippee bottles with size 1 tests but these are far to fast for him. He spends the whole feed coughing, spluttering, gulping, finishes the feed in about 5 minutes, then burps and it all comes back up. Does anyone know any other bottles with a much slower teat that he actually has to work for the milk and slow it down? Thanks
