This is so convenient!  One of my little nephews had a large head and my sister had to struggle to get clothes over the poor child's head.  She was thrilled when she found some onesies similar to this one so that she could dress him in appropriately sized clothing without having to smush his head and make him cry.  I anticipate my little one might have similar issues, so this seems like a good choice for us.

I like the thick fabric which seems like it will hold up well and that there are extra snaps so these can be used longer as baby grows.  Good quality and convenience are worth paying a little extra for in my opinion.
