Milk intake

Mine 18m already, fully breastfeed when at home & pump during work. But I realize my milk almost drying out. Thinking to supplement with formula or fresh milk. But dont know which type

my 18mo is now drinking 240ml 2-3 times each day, she used to drink 180ml 3-4 times a day at 15mo

Do BF upon demand. For milk formula, can follow formula tin as a guide only.

I tink 170ml.. now my gal 21 mths drinking 180ml…

my baby 1y5m drink 4oz-5oz every 2..3 hour…

230ml twice or 3 times a day
