I've just bought a quilted anti allergenic mattress protector (not a waterproof one) for my cot as I felt it was a bit bare and hard for baby just with a sheet on its own. Plus I just wanted another layer to keep the mattress clean same as I do on our own bed. I am just wondering now is this safe for a baby under one year old?? I bought in Mothercare and I did ask and they said it was ok. But I said I would check again with you folks here. They hadn't me entirely convinced in the shop as the girl had to go ask another lady on the staff. Can anyone advise please?
