DD is at daycare and apparently she doesn't like some of the nipples I send.  We use playtex drop in bottles with the slow flow nipples. I nurse her at home so I don't know which ones are good since they all look exactly the same and I don't give her bottles.  I'm wondering if I should just move up to medium flow.  DD is 5 months. Has anyone switched nipple size?
