Weekend mornings with my 4-year-old turn into a race against time

Lately, weekend mornings have become a stressful scramble instead of the relaxed start I hoped for. My 4-year-old insists on choosing his own outfit, which is adorable but often means he takes 20-30 minutes trying on clothes and changing multiple times. We’ve tried laying out options the night before and setting a timer, but he either ignores the timer or gets upset when it goes off. Meanwhile, breakfast is a battle because he wants to eat very specific things that aren’t always ready quickly. I’m aiming for a smoother routine where we can enjoy our mornings without feeling rushed or frustrated, but right now it feels like a constant tug-of-war. We don’t have to be anywhere super early, but I’d like to have enough time for a calm breakfast and maybe a little play before heading out. Has anyone found a way to keep a preschooler engaged and cooperative with morning routines without turning it into a power struggle? How do you balance giving them autonomy and keeping things moving efficiently?
