Hello everyone! So I have a 15 month old and I’m trying to wean him off nursing at night which I’m already dreading lol. I wanted to know if any of you have an idea of a soppy cup that doesn’t leak if a baby uses it laying down. My son doesn’t like bottles what so ever except if it’s a soppy cup. Thanks for your help!
