Size 2 diapers?

Our girl is 11.5 weeks old and about 14 pounds. She has always been the queen of blowouts. She just has powerful poops and even when she first moved to size 1 diapers, she had blowouts. However, this week it’s literally been everyday. Twice yesterday, actually. The size 1 diapers still seem to fit her around the waist, but do you think I should switch to size 2? I feel like it’s super early for size 2! We also did a diaper raffle at the shower and I have a ton of size 1 diapers still left to use. 🤯
