Hello mommies. My baby son has just turned a month old yesterday. I have to visit my gyno tomorrow for some check ups. So my son will be staying with my mum and will be depndnt on formula feed for half of the day. I have only given him one or two feeds of formula since his birth so have no idea actually. Plz tell me how much formula should she give him per feed? Also I have formula similac. Is it okay or any different brand will be good? My bub is on breast feed till date.
