My daughter was born eight month two weeks with a birth weight of 5.6oz and by 7weeks she was almost 11pounds now at almost 8months she is just 13pounds .she is very picky and cry upon seeing bib now eating 4oz. with me forcing her.People keeping saying she is tiny.Her milk been change 5times and would take breast, don't eat from bottle but the doctor said she has acid refluex and started her on solid foods on 4mo but still does work, she been on 3 diferrent vitamins but none ever helps.But her doctor said she okay and way advanced for her age but still wouldn't eat.Due to freguent change in baby sitters, am having so many enemies, and the only thing she like to take is just plain water,am always in tears and worried day and night.
Am sorry u r having so much trouble feeding ur son. Patience and persistence keep trying, feeding him whenever he wants and try different things. I would also recommend Pediasure that help my son to gain weight or mix his milk with Nesquik or other flavorings. Just whatever u do do not try to force him to eat because then for sure he won't eat. Best of luck
