Hey yeah I have I tried it it at 4 months but she wasn’t ready she kept choking, spluttering and trying to avoid the teat - so went back to size 2 then when I felt she was ready at around 5 months 1 week I tried again with lots of breaks she was quite out of breath trying to keep up with it but she got the hang of it within a week
I’ve tried it around 5.5 months and it just went everywhere and he pulled away too fast but his clicking speed the bottle so I think 2 is too slow 3 does seem like a big jump
We have actually started to move onto number 3 now. There is definitely a transitional period with these! The best thing to do is to start in the daytime so they are more alert and able to adapt and learn. There will be a bunch of spluttering and coughing but they are perfectly ok. They will eventually learn it! Took our LO about 4 or 5 days to absolutely master it during the day and night. You just have to bite the bullet and persevere with it. They will pick it up in no time x
2 is too fast for my baby she’s still on 1
