We’ve used the bibs deluxe dummies almost exclusively since my daughter was born. She loves the round latex dummy teats - I guess you don’t always have a choice over which one they like, but these are the best we have been able to find. I love the simple, tasteful aesthetic of these dummies and it’s an added bonus that the lifting rounded shape of the plastic means my little girl isn’t left with indentations on her face after using. The fossil grey/mauve options that we purchased this time are lovely dusty violet/almost plum shades and they’re divine. We swapped over to the size two dummies when my daughter was six months and it was a very smooth transition. She seemed ready for the bigger teat size, but it wasn’t too much of a jump. We tried to move up to the next size at 18 months but she hated it! I’ll review the next size up dummies elsewhere but the teat is huge in comparison and she couldn’t handle the difference. She is still using this size at almost two; we’ll likely wean her off her dummies soon. We tried the Frigg dummies, which have a similar aesthetic and were slightly cheaper, but the dummy ring clattered around a lot. My daughter liked shaking them for a rattle effect when we were trying to get her to sleep at night. The dummy rings on the Bibs dummies are moveable, but you can also move them to a position in which they will remain fixed, and no annoying rattling. They’re also quite hardy for latex dummies. The instructions state not to use beyond six weeks, but I have stretched a bit longer out of ours, especially given that my daughter only uses them for nap and bedtime at this age. Obviously I check it carefully before each use for damage. All in all I’m a very big fan of these dummies.
