augbb,
i've assured u b4 tat watever amt u r feeding ur bb is fine, juz like wat e PD has assured u. since ur boy cries 4 milk so badly, do u wanna let him cry & "underfeed" him (which is so impossible since he cries for milk when he dun get enuff) or juz feed him "enuff"? is feeding him enuff considered over-feeding? 2 me, over-feeding is when ur boy is full, not fussing in between feeds and u r shoving him wif more milk OR when ur boy finishes 4oz n cant drink anymore BUT u keep shoving e bottle into e mouth 2 make him drink more - tat's overfeeding 2 me.
for BF bbs, we always say, "feed on demand". i tik this phrase applies 2 all bbs. if ur bb wants 2 drink and is able 2 drink up 2 XXoz of milk (be it EBM or FM), u as a mummy will 1 2 feed him rt? u cant b telling a crying bb, "darling u cant drink 4oz now bcos e milk tin says u r only drink 3oz at tis age"
u being a 1st time mummy, i applaud u as u r doing very well n ur boy's doing very well too. it's normal 2 worry n when u worry, it's bcos u hv a sense of responsibility towards ur boy. dun worry too much abt overweight bbs, overfeeding and all. there'll b more & bigger worries 4 u in future such as fever, illnesses (stomach flu, teething, runny nose, phlegmy cough), eating solids, not eating well, terrible twos, etc.
let me assure u again tat since e PD said it's fine, juz feed ur boy. in fact, i was even planning 2 tell u 2 increase ur boy's milk intake by 1/2oz every 2wks or as per his demand. i've come across a bb who drank 5.5oz EBM at 6wks. i dun deem tat as overfeeding. 2 me, e mummy's doing her best (like u) 2 meet her boy's milk demand.
