Newborn Pee

Hello mommies! My LO is just 3-day old today. I'm breastfeeding her and just wanted to check if ilan diaper ba dapat ang may pee siya and gaano kadami to know na she's getting enough milk supply?

Nag popoop siya sa diaper (millie moon) however ang hirap idetermine if may kasama ba pee yun. Usually kasi yellow pa din indicator ni millie moon diaper everytime we change nappies.

TIA!
