I have been trying ds (8mo) with a tommee tippee first cup once a day. On the first ever try (6mo) he made a really good attempt at it and I was very encouraged. However it has been downhill all the way from there, despite me trying him with it at his 'best' time of day. It doesn't seem to make any difference whether he's hungry or not - he just wants to chuck it across the room (and so do I now!) At this rate he'll still be on bottles when he's 30! Aaaargh need reassurance
