The MAM Self-Sterilising Anti-Colic Bottle Starter set is a total solution for feeding babies from birth until their first birthday, containing everything you’ll need to give your baby a better feeding experience at home and on the go. MAM teats are available in size 1 (slow flow) for birth onwards, size 2 (medium flow) for 2 months onwards, size 3 (fast flow) for 4 months onwards, and size X (cross cut) for 6 months onwards. MAM teats are interchangeable with all bottles in the MAM range. Ages listed are only suggestions, as all babies grow at different rates; if you notice that your baby is trying to suck harder to get their milk more quickly or shows signs of tiredness or frustration while feeding, it is probably time to move on to a faster flow rate. The orthodontic teat is ideal for baby’s jaw and teeth development. The start soother is recommended from birth to 2 months of age.
