Babies are very sensitive. Any weird and untested chemicals and ingredients can be harmful. Their skin is soft and thin and can absorb many more chemicals and they put everything in their mouths. Knowing all that, do you really want to take a chance with these untested products. Recalls of baby products in dollar shops are very often, and materials used are the most common cause.
If you decide on buying something some of these things, then you should keep it at a safe distance from the baby. One mile should be enough.
