oh cool il check it out thanks sarah! my bubba is drnking 125mls i make it up with a little extra water to help with poos. at 3wks tho she was only taking about 80mls my theory is if lucy eats the whole bottle she will go to the next feed but some feeds durin the day she leaves about 40mls out of the 125.. dont stress if he doesnt eat it all i think they have to build up to finish the whole bottle IYKWIM? HTH (((hugs)))
