Oh dear, I totally understand how we doubt every single thing we eat for our little angel. Blueberries are so full of goodness, I used to feel so happy thinking I am giving my baby the best. Enjoy your treats, it's such a beautiful phase of life!
Listen, dont overthink so much, blueberries are absolutely safe and actually very good for you. Just make sure you wash them properly before eating to remove any dirt or chemicals. Eat them in moderate amounts and you'll be perfectly fine.
Aiyyo, my MIL was a bit unsure about English fruits, but my doctor told me blueberries are totally fine and actually super healthy. I used to wash them nicely with warm water and eat daily. Just ask your gynac once to be sure, but usually they are great for baby.
I used to eat frozen blueberries during my pregnancy, and even after my C-section, they really helped with my recovery because of the fiber. Just wash fresh ones really well to avoid any stomach infection, post-delivery healing needs us to be extra careful anyway.
Honestly, I had crazy cravings for berries in my second trimester and ate a cup of fresh blueberries almost every day. It did not cause me any issues at all and tasted so refreshing. But everyone's body behaves differently, so see what works for u.
