6 month old has to suck very hard nothing comes out
6 month old grandson wants to hold bottle, so I purchased this and sent it. Mom says he sucks but nothing comes out. She tried to make hole larger, but with no success. Can the nipple be adjusted to allow flow?
The Nuby 3 Stage Standard Grow Nurser is designed with a patented variable flow non-drip nipple that can be adjusted for slow, medium or fast flow rates. If the nurser is not functioning as designed, we suggest that you contact Customer Service at Nuby directly via email at [email protected] or via telephone at 1.800.588.6227.
