my 12 month old does it all the time too , have u tried getting in the bath with the child ? i found mine was more she wanted me in there playing too . i have a shower over the bath if im haveing a shower she wont do it .

also i have small no slip star fish as well as a mat . the star fish worked a treat for a week , maybe just like a new toy would . and maya could get out of the up right and the semi recline bath seats at around 7 months i found them dangerous .
