Hello mamas, please read this!!! I have the "Happy Baby" brand for these and I did read they say to use within 5 days of opening the can, but don't expire until months after. After reading this, I'm throwing both cans I have away and just buying fresh even if my baby boy doesn't finish the entire can. I rather buy a new can every 7 days, because their safety is first! Thank God this baby girl is fine, alive and healthy!
