i have been around, not always under this name though, i remember you wilkie !
GF - well, what can i say? lotsoflibellousthings so i won't !! it works for some babies and parents
but it sounds like your baby would not tolerate being made to wait 2 hours for a feed
you will only be distressed as will he, a newborn has a small stomach, which needs filling little and ofnte
as an adult, i like to have a drink more frequently than 4 hourly !
3 oz really is not a huge amount and if it is too much he will bring it back up
it is really hard not to compare, but i had the same with my two, in reverse. DS fed all the time, like a bottomless pit. at 12 weeks he was taking 6 - 7 oz, whereas DD would struggle to take that at 12 months. some feeds would literally be 1 oz.
you have to take each baby as an individual and trust yourself to listen to their needs and respond to their cues
sounds like you are doing just fine
