Ay normal lang yan, mommy! Five poops a day is actually very common for breastfed babies, especially at 4 months, a few of us moms noticed the same thing with our babies kasi breastmilk is really easily digestible. As long as the poop is soft/mushy (hindi hard), may good color, and baby is happy, gaining weight, and wetting enough diapers, you're good na! But kung concerned ka or may changes sa color, consistency, o may signs na uncomfortable siya, mas okay na i-check lang with your pedia para sa peace of mind mo.
