Transitioning from Nuby Sippy Cup to Hard Spout

Go to a regular cup, and have him drink at the table. There is absolutely no reason that a child needs to carry a cup around - especially if there is anything other than water in it. Serve a drink while he is at the table or in the high chair, have him finish it, and then he can go off to play. Get him in that habit now and you won't have nearly as many issues later.

Once my kids were 2, I also got them sports bottles, where they can close and open the lid. But it's for water only.

Some might call me mean, but I didn't give my daughter any other choice. I switched and after a few hours, she switched. lol

I'd just switch to an open cup except when you're out and about. That's what feeding and speech therapists recommend for proper muscle development, and really, sippy cups are quite a new invention. My kids switched at a year, and were able to handle a cup at their level with relatively few spills by about 15 months.

I second Julia N's response.
The BEST cup for a child (one year +)
is a basic training cup (old fashioned) that they can really sip from.
No need for extra sucking "no-spill" features (that just a bottle in disguise)
A DENTIST will confirm this (and one dentist even GAVE us a free cup)
You just put a small amount of liquid in, and if they're too young to control it themselves, you help them until they can do it all alone. PROUD, BIG BOY!

My very favorite cups are the new Nuk or any Gerber cup. They are seriously the only ones that I have ever found to not leak. I have never had my babies protest the transition from a bottle with the Nuk sippy and they are super easy to clean. I am surprised you said the Nuby was easy to drink from. I bought one for my first son once and when he had nothing gone from the cup after a long period of sucking on it I actually tried to take a drink from it myself. I found to get anything from it you actually have to slightly bite on it and suck at the same time. Maybe that is where the problem is, he may not know how to just suck on it. Just a thought. Try the Nuk active cup, the spout is silicone like the nuby but has an easier more natural flow which may help him to transition to a harder spout later. It also doesnt leak! Good luck!

straw cups. walmart has a set of 4 plastic cups with lids and straws for less than $3. i love them because they are so easy to clean. there are no impossible to reach crevices for gunk to build up in. i just use pipe cleaners to clean out the straws. and if we lose one or the baby drops it and it gets run over by the stroller and stepped on, i lose very little money.

Just keep offering...that's all that will work. But I'm glad you posted this because I am currently using Nuby's because I liked the soft, breastlike feel...maybe I will switch now to avoid the rebellion!

get him the ones with the cars cartoon characters on them. i had my son on nuby soft sippy cup and changed him to a sippy and these were the only ones he would use. if you are using what i think you are you can buy new spouts and they wont leak anymore after a while of being chewed on the start leaking but if you buy replacement spouts your good again. the ones I use have no handles
