My baby who's a yr old and 8months haven't pooped for 3days already. She's breastfed, but I'm thinking if it's because of the banana?

That is not a good sign, try to use Glycerin Suppositories. You can buy this at any drug store. This will help your baby to poop, ang sinasabi kasi ng pedia kapag breastfeed dapat daw hindi constipated si baby. Ask pa din your baby pedia

Hi mommies! Okay na hehe I just got paranoid haha but hooray my little girl pooped already hehe

Try giving your child more liquid. If she's a bit restless, it is best to bring her to your pedia.

Good if she's breastfed. Give your baby water also so she can digest regularly.
