I'm not a fan of letting a baby cry it out. Honestly, I don't know if I could let Loki cry until he falls asleep. I have no problem with a bit of fussing, as I believe having to wait a minute teaches a child to deal and have patience, but full on crying - we don't do it. (Well, we do, with Ander. But Ander is old enough to understand that we love him but won't give in to his fits.)
That said, I HAVE to do something. Loki is keeping me up all night. He screams and cries, at random, even when we are co-sleeping. Some nights, he nurses a lot. Others, he refuses to nurse at all.
I am so sleepy, even with Alan doing the crib runs (getting him from the crib when Loki screams EXACTLY FIFTEEN MINUTES AFTER I ENTER REM SLEEP EVERY SINGLE NIGHT...sigh...and putting him in our bed), that I'm scared I'm going to crash my car on the commute. I literally cannot keep my eyes open. It is bad.
I don't think I can fit in a daytime nap. Take today's schedule, for example. Wake at 6:45 to nurse Loki. Bring Ander potty. Get both kids and myself ready and leave the house to arrive at mom's at 8:30 a.m. Then, I eat breakfast, check work e-mail, return one client phone call, and it's 9:30 a.m. Get Ander ready for playdate at the library at 10 a.m. Return at 12:30 to my mom's, eat lunch, and I only have about two hours left to work before childcare is done. If I nap, that takes up the work time. Sigh.
With Ander, we did a more gentle sleep training, where we went in the room and patted his back, and stayed nearby when he was awake, but didn't talk to him. But I think Ander was older.
I've heard people say that having a child means lack of sleep and parents choose it, so they should just deal. Those people are judgmental prats. (There, I said it. Ha!) Most important in this equation is that I'm falling asleep while driving my children, so something has to change.
But I don't think Alan or I can handle Loki crying. It's not even a philosophical objection. It's a physiological one.
