Ok so tomorrow morning i going to ring my HV or doc because im really worried but thought id see what you lovely people think. We have always fed Zacoiya on demand since day one and he always started to show signs of getting hungry within 2 and a half - 3 hours and if he went 3 hours he would be screaming - by 5 weeks he was on 5oz bottles and then went into 6 oz bottles at around 9/10 weeks. he had always guzzled his bottles as hes always been quite a hungry baby. couple of weeks back he went through his 3 month growth spurt and was taking 8oz bottles so we upped his bottles to 7 oz and it evened out his intant during the growth spurt - when he finished the growth spurt he was happy on 7 oz bottles but took around 6 and a half oz. but for past week hes just not been interested. - he has his last bottle at 9:20pm (normally guzzles this bottle 7 oz) and goes till around 6 ish till he wakes for a feed . Hes taking a max of 5oz at each feed normally around 4 and a half oz - and we are having to just offer him his feeds as hes going 4 hours without showing any signs of being hungry!! and i get worried leaving him any longer so give him a bottle and he takes between 4-5 oz. He normally would take anything between 30 - 35 oz in a 24 hours period but been monitoring him resently and hes being having around 24 oz in a 24 hour period im really worried about him because it just dont seem like him - hes normally such a hungry baby does anyone have any suggestions as to why hes suddenly like this?
