These were a life saver for me. I brought the Mam starter pack which only come with size 1 teats. When my baby was feeding he was struggling with just how fast the milk was coming out. I ended up finding these size 0 teats and they were perfect! Great speed and made feeding much easier.

10000% recommend getting this 0 teat for newborns. The size 1 teat was too quick for my daughter so this was perfect for feeding!
