Tired

I'm sitting in my living room at the end of the day and I am so tired I could cry! The boys are both in bed, the baby was very restless today so we didn't have a nap, he wouldn't lie down, he would only sleep in the carrier which wasn't much help for my nap. I could've had one standing, like a horse maybe? How do parents who don't carry their babies manage? I really feel for them... little one has an average nap time of 20 minutes alone, in the carrier or the wrap he can go for ages. I wanted to post something profound but I'm too tired... I've been wanting to go back to some sort of Buddhist practice but when exactly do I sit down and meditate on my own? I suppose babywearing meditation could be a new technique, or does it exist already?
