I have just started weaning my 23 wo ds and am really unsure on portion sizes. He was having 210ml/7oz of formula every 3 hours. I have replaced his 11am bottle with veg and fruit, and he's currently having 3 ice cubes of carrot with baby rice and then 2 cubes of fruit. He's then having 2 more cubes of fruit with his 5pm bottle (but with the same amount of milk as before).
I'm really worried about overfeeding but just can't find any guidance in portion sizes? I don't want him to go hungry!
