Shower time

My 5 year old daughter has decided she wants to take a shower every night instead of taking a bath with her younger brother and sister.  This is one of those things you never really consider, but makes you realize how quickly your little kids grow up.  I know it's a simple shower, but I felt like saying "No! You're too little! I want you staying in the bathtub with your siblings forever!" I didn't say those things, of course, but it did make me kind of sad to realize she's old enough to do something simple by herself like bathe herself.  Of course, she still needs a little help with shampooing her own hair in the shower.  And, with kid #4 coming in March, it will be a little difficult to have 4 children all sitting together in the tub at bathtime.  I understand logically all of these things, but it still made me a little sad.  Maybe I should blame that on pregnancy hormones.
