Hi C.,
I had my children off their bottles when they transferred from formula to milk. I also never gave them juice in their bottle, it only came through their sippy cups. Therefore, they knew in order to have juice they had to drink the sippy cup. So when they had milk for the first time it too was only available to them in the sippy cup. As with most children, once they taste the milk they never want formula again, and they'll know it's only going to come one way, in a sippy cup. It worked for both my children, my nephews and nieces. It doesn't take long before they completely get this, maybe a week or so, weening down bottles if you have to, to only bedtime and nap time. Good luck!!
