Hi there i have just bought some MAM BPA free bottles, and have been trying to find the MAM brand teats, but have only been able to find the newborn size, which is what comes with the bottles anyway! we use thickener in DS's formula, so i know that the teats will be no good for him. we have been going well with the avent #2 teats, and they look the same size as the MAM ones, but i am just wondering if anyone has used the avent teats in the MAM bottles? i have tried using different teats in different bottles before and they always leak. if i can get away without buying new teats that would be great as i have just replaced the avent ones a few weeks ago! alternatively, does anyone know where i can buy faster flow MAM teats in perth? thanks!
