We purchased these as I was tired of trying to prop my baby up with pillows, or a book under the cot legs. I found these and what a great purchase - I have bever looked back! I think they are the best, most practical thing I've bought.. I rate them so highly, I have bought them for friends as gifts when they have had a baby instead of clothes!
Granted if they dont fit the cot legs they are useless, although all the cots I have seen they have fit.
They do aid sleep when my baby is congested through colds or other sickness.
People should be happy if purchased
