I have a 5 month old baby and my monster-in-law wants to give her a bottle of tea, is this OK for babies?

you need to tell your mother-in-law to take a hike

Actually, doctors recommend tea as a light laxitive for infants. It's pretty common, and is supposed to help with upset tummies. I gave my baby tea when he was small.

No and you should make sure she doesn't. Tea has caffeine which isn't good for a five month old (plus, their brain is developing and this could hamper its proper growth). Opt for milk or breastfeeding, etc.

You've got to be kidding right??? That stuff is full of caffeine, what is you monster in law trying to do....

IT IS YOUR BABY NOT YOUR IN LAWS! TELL THEM TO GET LOST! IF THEY WANT TEA THEY CAN DRINK IT BUT NOT YOUR BABY! IGNORE YOUR IN LAWS DO YOUR OWN THING!

NOT a good idea, loaded with caffeine

If you don't think it is a good idea, then don't let her. It's your baby.

Tea contains both tannin and caffeine,

:O You cant give babies tea!!!! Whatever you do, dont give him tea!!

Tell her if she does that you'll B**** slap her. Is she out of her mind?
