nikbrad i did that when i first put him on the thickened formula forgot to change the teats and he was sucking and getting nowhere lol. The teats i use now are the cross teats at the top of the teat not the side of the teat as the side cross teats are to hard for him. I am yet to get him weighed this month but every other time i have gotten him weighed he has been on a good curve. Yeh he seems to wake between 2 and 4 during the night as he is hungry. when he was 3 months he got into a good routine 11:30pm untill 6:30am, and then all of a sudden that went out the window. Well I have been demand feeding because of his eating habits, I tried to change this the other day because i would like to get him into a routine but I cant because he wont eat. It says on the tin 4 to 5 bottles a day but he does not have that much. i have him booked to see a doc on the 5th of next month but it just seems so far away. kimbaz i try and offer him water as much as i can through a bottle but thanks for the idea on wet face washes, ice cubes. one question os there any chance he could be lactose intolerant?
