Have just had two Motherease swim nappies delivered - have always used the Mothercare ones before.
Motherease have a poo catcher bit in them, but I don't think they'll stop a wee - do any of them stop wees, or is that just wishful thinking on my part? Thinking about it, not sure the Mothercare ones would have done, either!
DH will testify to this as he was once carrying ds1 on his shoulders on the way back from the beach. After a few minutes he felt a wet warmth spreading around his neck and down over his shoulders. I laughed A LOT .
we have a couple (Mothercare, Ladybird/Woolies) that feel like they have a plasticy liner under the towelling inner - they would keep in a poo no problem, but I reckon if (for example) you were carrying a baby wearing one on your hip on your way into the pool, it'd stop a wee actually running down you.
Not poo, just wee. DH was holding DS before his swim lesson (me in pool, DH watching and holding DS for me). On DH's shirt. DH then had to go back to the office for the remainder of the day in said shirt !
