DD1 is now 7 and for the last couple of weeks has asked to have showers by herself rather than share a bath with her 5 year old sister. This is great and a sign that she is growing up although does seem to make it a bit more time consuming for me as I'm used to just putting them both in the bath together. DD1 does well in the shower but does need a bit of help with getting the shampoo and conditioner washed out of her hair.
Just interested to hear what other kids of a similar age like to do.
