Hello, my baby will turn 4 months soon, and I’m constantly stressed about my milk supply.. I give two bottles of formula within 24 hours, and breastfeed the rest of the feeds. Baby sleeps longer and seem more satisfied after formula feeds, he sometimes breastfeeds for 40 minutes and after that when I offer a bottle he jumps on it as if he wasn’t drinking from me.. I want to continue breastfeeding but scared my breasts have low milk supply. Please advice.

PS Baby’s weight is less than average but within the parameters. He wets his nappies 5 times a day with one extra poop.
