I used a different brand when I had my son and discovered MAM when I was looking for bottles larger than 4oz.I’m so happy I found this brand! These bottles are so much easier to clean than the previous brand we were using. And I love that the bottom comes off for easy cleaning. I’ve now bought this brand in-store and I absolutely love their pacifiers as well!Buy it! These bottles are my go to! I’m a licensed foster care parent and I am amazed at how much this bottle brand works for all my babies I’ve had!Every time I get a new child placement I order a set! Its like this company’s shape of nipple is natural to baby, equaling fuss free feed to calm happy baby!Not as pink as advertised in the pictures but definitely does justice ... I love that you can break down these bottles to clean them unlike other bottles that have hard to reach places & u cant really scrub out all the areas you'd like to cause other bottles on the nipple & lid breakdown ... Definitely recommend ?????We love these bottles for our son. They hold plenty of fluid and don’t cause gas and his spitting up has greatly reduced since using these bottles exclusively.I received one of these as a sample and my daughter absolutely loves them. She can’t latch on a Dr browns or anything like them with the rounded nipple, but the flat design of the mam nipple she took to right a way. I love how easy they are to clean and sterilize. Will use these until she is no longer bottle fed!!!These bottles were a life saver for us. Our son spits up a lot and these bottles, with his A.R. formula, helped him tremendously. The nipples on the mam bottles, and the pacifier are the only thing he'll use now.The bottles are very good and my kid loves them. I appreciate the variety of color choices as well. Just make sure after you use the bottle to fully take apart the bottle to clean and sterilize them as formula residue will build up if you don't which gets gross. High quality and great for the price!Tried so many types and these were the only ones that helped my babies reflux issues. The holes in the bottom are such a clever design gets all the air out as she drinks! Easy to clean, love that they can be microwaved to sanitise every now and again tooMe encantaron estos biberones, mi bebe cuando nació aceptó los avent natural pero después de meses de solo lactancia ya no quiso el biberon y mamá tiene que regresar a trabajar, tardó más o menos un día en agarrar estos biberones mam pero ya se adapto y ya le gustó, puede tomar sin problema, son muy bonitos, prácticos, me gusta mucho su diseño aún que me gustaría que ubiera más variedad ya que volveré a comprar masMi bebé de 4 meses apenas se está acostumbrando al flujo medio.Amo estos biberones y mi nena también son los que mejor agarra, de recién nacida le daba el flujo lento, y los chupones también son una maravillaEstamos super felices, me ha costado encontrar mamilas que le gusten a mi bebe, probe muchas, despues de leer los comentarios me anime a pedir estas y le encantan, se adaptan muy bien a la boca del bebe, no le ha causado colicos, se lavan muy facil y son lindas.Buenisimos! Estuvimos batallando para que el bebe aceptara el biberon casi 2 semanas y estuvimos probando con varias marcas. Como el chupon mam le encanta decidimos probar con el biberon mam y fue instantanea la aceptacion. Le sale el flujo perfecto, ni mucha cantidad ni muy poco, y son muy faciles de lavar. Compre uno para probar y luego regrese a comprar mas porque en verdad son excelentes.
