going to introduce a sippy cup at 6 months. which ones who you all prefer?

I don't think it is. They are both soft nipples. my daughter prefers a hard cup. But she still loves her nuby.

@ya0515, I was thinking a nuby. is it a hard transition to the sippy nipple? cause he's picky with bottles.

I got my daughter the Nuby cup that has the bottle nipple. Also had the cup nipple that you switch to when ready. She's almost 1 and still uses it with no problem. She still prefers to use the handles too.
