My foster daughter has been growing like a weed! When she came to us a year ago she was 27 pounds at 7 months (yes - you read that right!!) and weve struggled to find her diapers AND to keep her healthy with her weight. Now that shes going on 18 months I transitioned her to pull ups for ease of use and because size 6 diapers can be tricky to find. I bought size 2T/3T pull ups from Huggies but that fit her SOO tight and I didn't like the fact it had such gaps in the back. We had blow outs EVERY day. As soon as we switched to Pampers and went up a size it has been AMAZING! No more issues, no more blow outs... and one happy toddler!
