Baby is very big and in size 4 nappies at 4 months. I struggle to get nappies that fit as they are either to big on the back/ waist or tight on the leg causing marks as I have to really struggle to stretch the tab to close them. I think the pull up style nappy would offer more stretch and cover around the waist. The brand I use the pull up style are the same for absorbency as the normal ones has any one used pull ups on small baby ?
