I really don't think I've got the technique right! Have given up on bottles after bf DS first refused Tommee Tippee when he started teething, then the Advent ones (which had been acceptable to start with!). He will take milk if it take the top off the bottle and tip little bits into his mouth at a time, but I seem to get at least the same amount on him as in him! Have ordered a Doidy cup from Amazon, but really need to get the technique right as I go back to work in a couple of weeks. It's not desperate until March (in Feb I'm only working 5 hours a day so if it comes to it I guess he will just wait for me), but would feel a lot better if he would take milk from something when I'm not there! He is 17 weeks now.
