In fact, if BB can keep to use the old 奶咀 that ok. Because my sons changed the 大奶咀 when they are 2 years, but the comment not so good. When I keep to use the old size 12 - 18 months, they drink the milk . Now, they are 3 years old la. , I only made the bigger hole in 奶咀 , I think, they are suitable the old one & easy to handle to drink.
or, the new 大奶咀 is not soft , bb spends more power for drinking. You can try to boil many times to make it softern, or keep the old one la...
Thanks for your comment, I changed back to the old 奶咀 except the nite time because baby can drink the milk when sleep. However she seems do not recongnise the differnet of the 奶咀. I want to change becauase I think it will be better for the shape of her month (since her month / teeth already bigger than before). :wink: :wink:
