My little one is usually on just under or just over the 500ml so we pop it in her bedtime bot each night x
I have started putting vitamins into my little ones bottles now as he is eating more food than milk so isn’t quite getting the 500ml a day now. But while he was predominantly bottle fed we didn’t give the supplements because the milk had them (formula fed baby) x
We do but only on days he has less than 500ml 17/18oz (my brain works in oz) lol more often than not he needs them, but we try sneak as much formula into his food as possible to get his ozs up x
My baby only had them because he was premie so for his morning bottle he has iron supplements and multivitamins called Abidec that he gets on prescription from drs but you can buy it in the store
