Weird habits after having baby/child

Just for interest. What weird habits or practices do you mummies suddenly develop after having a baby/child? Something you used to not do, but now do due to baby/child? Or perhaps something you used to do but now don't. For me, I start sleeping with my glasses on and my hair tied so I don't have to put them on to check on my baby. Also started wearing clothing that can go bra-less even when going out so it's easy to feed my baby if needed. What do you mummies do/not do after having a child?
