put it in a bowl of warm water to let it warm up.thats what nicu told me.

Okay! Thank you!

Run the bottle under hot tap water or boil water on the stove top and set the bottle in there.

I heat up water in a coffee mug and let the bottle sit in it for a couple seconds

best if you put the bottle in a hot cup of water or use a bottle warmer

Never hear bottles in the microwave always stove top

No never

no bc you could destroy it
