hi my 10 wk old has suddenly no interest in his bottles. only 2 weeks ago i was worried he was drinking too much.considered changing him to hungry formula but just uped the ounces instead...he was taking up to 7 ounces. since wknd its a struggle to get him to take bottle. he is in good form between feeds and sleeping well but will only take a couple of ounces before messing with it. he only drank 2 ounces between 11am and 5.30 this evening. he wouldn't take any of last bottle tonight. he has a slight cough and cold so had him checked by gp...no sore throat or ears. im baffled...we couldn't keep him fed last week!! any one else experience this with little ones?
