I noticed that my lo who's on his 10th week makes less wet diapers at night. We're on EBF. Lo's active when awake and no fever. Is this normal?

EBF babies are essentially light wetters. As long as you don't see any worrying signs, especially signs of dehydration, then there shouldn't be any worry.

As long as your baby wets a diaper with 2-3 hours, he should be safe. Generally, EBF babies pee just 2-3 tsp in 3 hrs.
