Advice needed please guys, I was exculsively breast feeding my son until he was 3 wks old then I introduced a bottle of fomula just once a day (I wanted to do combination feeding and was told to introduce a bottle between 3-4 wks) my son is now nearly 10 wks and i've found for one reason and another that I am now mostly bottle feeding him, He has 4 bottles during the day and just a breast feed at night, he has his last bottle at 9pm and goes down sleeps through to 4.30/5am which is brillaint I know but as he's only actually waking once during the night I am now just breast feeding once every 24 hrs.What I need to know is, Is just 1 breast feed a day enough to keep my milk supply up? I don't get that fullness feeling any more but when he feeds he does appear to be swallowing so he's obviosuly getting some milk, i'd like to continue with 1 breastfeed a day until he's about 6 mths but not sure whether this will work. Do I need to be feeding him more often to keep my milk supply available?
