Yes u can but it's better to introduce when they are 8 months old.

I gave my girl spout cum sipper from Mee Mee but my daughter chose feeding cup from Madela..... she's 11 months and still doesn't like sipper,spout or bottle for having any liquids....the cup has good mouth shape and easy for <u>her</u>

I'm giving avent sipper but problem is after drinking water that sipper he started biting my nipples while feeding milk. what should I do now?

Yes you can.

avent brand is <u>good</u>
