Cant give toddler a bath

im haveing an annoying issue in the sims 4 where my Sims refuse to bath their toddler. they will pick her up then just put her down in the same spot .i have seen this is an issue for others (athough most people say there sim will put the toddler in the tub then just take them out). i have tried every fix i can see but i cant get it to work there are no babys in the household and im stumped.
