My son is 7 months and he is breastfed, rarely ever uses bottles, so I’m guessing it will be easy to introduce cups, right? But what kind of cups should we get? Regular sippy cups, or maybe the bottles with the fold out straws? I don’t know if it matters, I’m a first time mom haha. He only gets bottles when my mom is babysitting so do I need to start giving him expressed milk during meals so he gets used to it or just save them for when I am away? Any advice would be useful!
