What do you find easier to give your preschooler. A shower or a bath? Maybe the question should be which do they prefer.
While showers were faster and more efficient I always used baths at that age. It helped them calm down, clean up and get ready for bed in a fun, playful environment with lots of toys to entertain them. A little time out for us both!
We did baths for Pre-School and began introducing the shower mid-year second grade. I loved bath time with my kiddos...it was one on one time!
For my 3 year old she has done showers since she was 2. If I tried a bath, she thought she should stand so a shower just worked better.
