I know there's a formula feeding board but more people on this one 21wks and weighing in at 20.5lbs. Exc formula fed, formula needs by weight equal 51ozs!!! 7ozs every 3hrs would be only way!!!!! Only getting 30-35 ozs into him, have to keep to 3-3.5hrs as reflux baby, frequency of feeds makes him wake often in the night though! Thinking of starting solids now to get him on 3meals and snacks etc as soon as so that the little monkey is full!! He might get done decent 'z's then What do you think? (He can hold himself up supported, can sit well in highchair (tried him with purée and he swallows well) and meets all the signs for weaning).
