Motherease work best with a booster/liner that snaps on with poppers - we use the stay-dry ones.
You can make you own liners with fleece or microfibre which works out cheaper.
Paper liners are useful in addition as you can flush them & the poo away but they can lead to the baby's bottom staying a bit damp & more prone to nappy rash.
You'll need wraps - motherease airflow are the best and fit over most real nappy makes. The totsbots wraps are rubbish (apparently).
BTW I'm not on commission for motherease, honest. I have a few totsbots too AND they're made in Scotland!
