First of all , this tub be difficult to inflate . the instruction say you can blow it up by mouth , but that would take hour . we have two air pump , but neither one have the correct kind of fitting to match the valve on the tub . we eventually get the right kind of fitting and inflate it . we baby be very active right now and the bottom of the tub be extremely slippery . she be slide all over the place . she slip and fall face down in the water a couple of time . I grab she immediately and pull she out , but I do not think this be safe for active baby . we will not be use this tub .
