My baby is 14 weeks old and is currently breastfed for all feeds except for one bottle at 5pm.
Today I realized that the Mam bottles I've been using only have size 1 teats in them. I need to move up a size but don't want to buy size 2 and 3 while he makes the transition.
Will it be OK to use a pin to make the hole a little bigger in his current teats or is there a reason why I shouldn't?
