Review: I love this it’s SUPER easy to assemble, easy to clean. I’m not yet sure of how durable the nipple is since I just started using it today but my 6 (7 tomorrow 😊)month old has two bottom teeth and has yet to bite a hole into it. It does seem durable and sturdy though. It doesn’t leak which is awesome since he just leaves his bottles thrown all over the bed 😂 I highly recommend the price is awesome. Everything about this little kit is great. And it’s easy to use for him. He is able to lay on his back, on his tummy, on his sides, sit up and still be able to drink his milk.
Review: Love them, started to slowly introduce it to my 6 month old and he took to them fast, they fit perfectly into the plastic ring that the Philips advent nipples do, comes with a thin straw clear which I really appreciate. Straw weight works well.

*by M***R on 6 January 2026*

Compré este kit de conversión para biberones Philips Avent Natural y ha sido una excelente compra. Es perfecto para la transición del biberón al vaso con popote, ya que facilita que el bebé aprenda a beber de forma independiente. La boquilla es suave, no lastima las encías y las asas ayudan mucho al agarre, lo que le da mayor control al bebé. El popote con peso funciona muy bien porque permite beber desde cualquier ángulo sin tener que inclinar el biberón, evitando derrames y frustración. Me gustó que el paquete incluya 4 piezas, ideal para tener repuestos o usar varios biberones al mismo tiempo. El material se siente resistente y seguro, y además incluye cepillos para limpiar el popote fácilmente, algo muy importante para la higiene. En general, es un producto práctico, funcional y compatible, ideal si ya usas biberones Philips Avent. Muy recomendable para bebés que están dejando el biberón tradicional.
