@Katie Awh thank you ☺️☺️
4-5 mos
They should say an age on them
If they’re falling asleep mid feed it’s time to change. But it’s 3mths then 6mths.
We just changed to size 2 (3 months next week) because my daughter was sucking so hard the size 1 teats were starting to cave in when she was feeding! She seems to be doing okay on size 2 although a little dribbly 🤣 Hopefully she’ll get used to them after a couple days and stop spilling bits out the sides!
They'll get frustrated because they're not getting milk fast enough and just stop drinking it. They may fall asleep mid bottle too. I pretty much followed the recommended ages.
