My 9mo is still content to feed before breakfast and at bedtime but is a right pain in the afternoon - she wriggles and struggles and gets distracted so won't do it for more than 5 mins max. Should I drop this feed? I have never given formula and don't want to start now as that seems like more hassle plus unnecessary expense but I don't feel I am achieving much during this feed and it just gets us both frustrated. She is above 60th percentile so a healthy weight. Could I give cows milk in a beaker? I know they can't only have cows milk as a drink but could it supplement 2 breast feeds? Grateful for any other experiences!
