Bro, you are probably not gonna like what I will say, but I have to. Kids need a routine. It gives them a sense of safety, since they know what comes next. So try to keep the times around the same for every daily activity, but most importantly the order, so they know after dinner comes teeth brushing, story time, and sleep time. They might resist it, and for sure they will test if they can break the routine, but after a while they come to accept it, and it makes your life so much easier 😉
