Re: 3 months old - how much per day?
I would feed baby on demand, whenever he or she wants. Make up sterilized bottles with 60 mL of boiled water in them and just give whenever they cry. I don't think it is really possible to over-feed a 3-month old. My son went through a tub every 5 days once I stopped pumping. I had been pumping 210 ml to give every 2-2.5 hours so I just simply couldn't keep up anymore with the volume needed. He did drop in his volume intake a little bit once he was on the formula, but only about 20 mL a feed less.
