Should I buy new ones for giving formula to my 11month old (he's exclusively breastfed but we're just starting to wean). Or is there something newer/better that I should buy? He won't take milk from a normal sippy cup, and I want to avoid bottles (which he never took either).
Yes, you have to bite them, and we have already replaced the spouts that had holes bitten through them. They now leak around the lid and where the lid joins to the spout. Sounds like its just time for new ones. It hadn't occured to me that they are 6 years old until I typed it here earlier.
