My LO started solids a month and a half ago and the doctor told us he should be drinking 2-4 ounces of water a day to help with the digestion/breakdown of solids. Ive tried giving him water through his bottle and a sippy cup but both don't work. I tried mixing apple juice with water, same thing. We're feeding him one meal of puréed food a day and sometimes the next day he will have very minimal poo and then a whole diaper full the following. He doesn't seem to show any pains/discomfort of constipation. I try everyday with the sippy cup. Any suggestions? Thanks!
