This is a great toy. I put in fridge to get cold and give to my g daughter and she chews on it for hoursEl único inconveniente es que pesan mucho y las veo adecuadas a partir de los 8 meses, hablo desde mi experienciaLove it for one of my grandsons baby shower giftThis is perfect for my baby because he rather have something soft like this for his teeth than the other had teething toy that he used to have.I bought this when my baby first started teething really bad at 4 months. He’s now 7 almost 8 months and still loves it.Had a slight chemical smell and concerned about exposure to baby. Other than this they're nice to grip and freezeHappy withMy baby is currently teething and he likes to nibble on these teething keys. I like how easy it is for him to hold and easy for me to clean! I love that it's colorful too which gets his attention as it attracts him.It soothes his gum pain while he's having fun biting and nibbling and with teethers, I think that's what's matters the most!I received these today. I put them in the steriliser for a clean before giving them to my 4 month old. Bad idea. I didn’t see anywhere on the packaging about cleaning and NOT to put them in the steriliser..... they are now burst, melted, and stuck together.. i have ordered more as they are on offer. I won’t be sterilising the next ones lolLa mia bimba di 4 mesi lo adora sta iniziando a mettere i dentini e questo è un ottimo gioco che massaggia le gengive.. E facile da impugnare per loro e riescono a manovrarlo come vogliono.. Non mi capacito però di alcuni commenti che avevo letto prima di acquistare questo articolo, gente che aveva provato a sterilizzare il gioco bollendolo nel acqua e si era sciolto, lasciando cosi 1 stella ma dico il cervello c'è l'avete acceso? E chiaro al tatto che un gioco come questo non può essere bollito ?poi in ogni caso vivete in un ambiente completamente sterile?! Che dovete sterilizzare ogni cosa.. Ma suvvia dai non è mai morto nessuno.. Anzi tutti anticorpi! Poi altri che si lamentavano della puzza di plastica che amana.. Ma non è assolutamente vero il gioco è inodore.. Lo ricomprerei per fare un pensiero a qualche bimbo.. Ottimo prodottoBaby loves these, especially when fridge cold, although she mostly chews on the ring part. She can hold them easily and they aren’t too heavy for her. I just wish you could unattach the keys so one could always be in the fridge for example. Seems silly to have 3 keys all out of the fridge when she can only use one at a time anyway.I was suprised that the packaging states that these keys are not suitable for ANY method of sterilisation which makes them unusable for babies under 12 months as all items must be sterilised before use according to the nhs website. The instructions say wipe clean only so it's not very sanitary for babies.I figured I can wipe them with a milton wipe after washing but it would have made more sense to make a baby item aimed at young babies suitable for sterilisation.When I first brought this I liked it however my daughter started teething at around 3 months so her holding of items correctly was off so I still had to hold the teething apparatus for her.Fast forward to four months her control in holding her toy and it ending up in her mouth is a whole lot better.She loves the colours it’s good for her eye coordination the blue key in particular I find she is quite drawn to but that’s my observationI also purchased the Nuby mitten which once again I find does take some getting use to but over the time becomes a good chew toy for babies who are teething.I would recommend it as it stops wet sleeve cuffs on clothing or at least reduces it slightlyAnd remember to sterilise it before use and after a days play.
