Something I promised myself with this pregnancy was that I would listen to my body this time around. Really listen. If I'm tired, I go lay down. I may not always sleep, but I at least put my feet up and rest. I figure there is a reason I'm so sleepy: my body is building a whole other person. No easy task.
So, I nap and I nap guilt-free - something I rarely gave myself permission to do with my first pregnancy.
I know not everyone has this option, tho'. But, even then, mamas I would encourage to give yourself permission to rest whenever it is that you can. o l know that jobs, clients, children need us, but the the dishes will still be there, the mail can be read later, etc. Be good to yourselves, whenever you can.
I also think, for me, it's easier to give myself permission to rest during this time in the pregnancy because I know that there came a time last pregnancy where I had TONS of energy - like run the vac at 2am, just have to totally reorganize the pantry and iron all the babyclothes energy (okay, some may call that insanity
). I figure it all evens out.
