Maybe try getting in the bath with him? I know what ur feeling Davis used to not mind car rides. But now he unbuckles his seatbelt and tries to jump all around. His attitude and feelings change from week to week. Sometimes autism can make u feel like ur walking on ice. Hang in there

Just when bathing! He used to be scared when he was younger and then was fine! Woke up one day and hated them! We have to have him stand in a baby tub in the living room and stand bathe him

Is he scared of water in general or just baths? Maybe try showers or a baby swimming pool standing up while you wash him down. Davis used to be scared until I added toys he liked and made sure no water got in his face.
