laura - Nina is tall, with wide hips, and I find the baby beehinds bamboo fitted work great with that. Also, they are very absorbent and can be used as a night nappiey.
With Emily, she is long as well, but lean, so I find the baby beehinds magicalls & the itti bittis work great with her. I do put the baby beehinds fitted on her, but only as a night nappy. The magicalls & itti bittis are a trim fit. They're both only day nappies, you can't use them overnight.

They're the only nappies I've tried so far. They work well, so I don't need to buy elsewhere.
