Happy 3 months my love!

So happy my son turned 3 months but in the back of my head heck I’ll be going back to work soon! Today we introduced him the bottle this morning. We thought morning time is the best time bec he’s hungry and not sleepy. So I pump for the first time since he was one month old ( I did pump to establish my milk and did full time breastfeed after a month) He did really well on drinking the bottle and drunk only 2 oz. how much do you give per feed??? Anyway we will give him the bottle once a day for 1 week for now until he get used to it.
