Just to let you know, I went to put this brand new sweatshirt on my youngest and saw, just in time (before dragging it down over his head and face), this nasty little sharp spike sticking out of the popper. It is from the baby dept of a very well known highstreet shop.
I don't usually feel the need to feel and check clothing for nasty pins or spikes before wearing but it just goes to show you can never be too sure...
