Target age: From 0 months Purchased on Amazon in September 2022. Used for about 5 months. (I have two, size S and M. This size S is a little tight, so I used the M size more often.) Please understand that this is a used item. Will wash and ship. There are no pets or smokers in the house. I am also selling other baby items. Please take a look. I will offer a discount if you purchase multiple items.
