Very fun for 7m old baby,I’ve always loved this brandI wiped it down with a damp rag before use, didn’t notice any irregular smell.Very cute and easy to use.The fill part is well made and straightforward to use, I haven’t seen any signs of leakage, I have had this out for a few weeks, I put it under baby’s jumper for his feet to be on and he seems to like that, He will still go over to it when playing on the floor to look at it.He also likes the pieces inside, when I drained it previously I took out the toys and he enjoyed playing with them out of the pad.I really like this option for a different stimulus for baby development.Nice size, not too small, but not too big to where it would be incredibly heavy when filled with water.Happy with this purchase !
