Brushing teeth/changing diapers/giving baths...help!

J

I don’t know what it is about being clean, but my 15-month old fights me on all of the above! I never knew a one year old could be so strong. The diapers are only an issue sometimes. The bath and teeth brushing are a struggle every single time. He constantly stands up in the bath and cries and wants to get out (sometimes attempts to-so dangerous). Makes it really difficult to wash his hair (which always has food in!). With brushing his teeth, he wants to do it himself, and won’t let me brush them. I’m glad he is independent...but I also want his teeth to actually get clean! Can anyone relate? Do you have any advice/suggestions on how to overcome any of the above? It’s like, he is 1...how hard can it be, right?! 🤷🏻‍♀️
