Routine...

My son is 8 months old he is on a routine where he gets a bath every single night before bed well tonight we had to skip the bath for the first time since we established the routine which was about 4 months ago. And every night when he sleeps he sleeps through the whole night from 7-8 until 6 am but tonight the one night he doesn’t get bathed he is waking up in the middle of the night. So my question is is it really that horrible that I didn’t bath him this one night? Why is it the one night he doesn’t get bathed he doesn’t want to sleep? 😞 it’s frustrating because now his schedule is thrown off because one night he didn’t get a bath and I just don’t like that. Is it going to be like this every time he can’t get a bath? Please share experiences. I guess my question is if you can’t do one part of the nightly routine is it normal to thro him off so much? Like one night without a bath his schedule is all messed up!
