These work perfectly for my 4 month old. They are easy to put on the baby, the padding is very light and soft on top of his head and you can adjust the size. The adjuster I would say is a little on the tight side so it's hard to get the clicks right if you are in a hurry. It's a fairly basic product, no bells and whistles or anything over the top fancy in terms of it's finishing's, but I will still give 5 for quality and value as I am comparing to other earmuffs on the market e.g. adult size ones from Bunnings and another baby one I've owned, which was nearly twice the price. The other baby one I tried had an elastic head-band instead of an arch and it was too fiddly to assemble and put on the baby, it was tight and rubbed against the baby's hair, and it kept slipping down over the baby's eyes falling off and collapsing. We should have got these ones to start with! Also happy with buying from Babybunting, they accept returns and exchanges which is very important if you are buying stuff online.
