Definitely try the swap up to size 3. Though i have to say we have done this, and it still doesnt always contain the daily poo-splosions! I'm just hoping she grows out of it...
There was a similar post a while ago I think and someone on here said to up vest size and nappy size and tbh this helped me loads!! If I start getting frequent blow outs I know it’s time to up sizes lol! I use pampers premium protection! X
I swapped to size 3 aldis around this size I think and haven’t had any accidents since! Buy a pack and give them a try on days you will be home just in case there are some leaks!
