Diaper Preference?

My MIL gifted my daughter a 6 month diaper subscription for Hello Bello diapers. They started at newborn and since my daughter was early we have just started using the gifted diapers. My daughter was in Huggies Snugglers in preemie and I loved them. I had no problems with fit or blowouts etc. I have been finding that the fit in the Hello Bello diapers is different, they seem much bigger in newborn and my daughter has had two poop blowouts since we started using them yesterday. Has anyone else experienced this? I had Huggies on my registry as they had always been my preferred brand, but I didn’t want to be rude and refuse 6 months of free diapers.

Thanks y’all!
