I got to have a blanket baby for four months.
Things have quickly gone south, and now I'm actually under doctor's orders that when Charlotte is awake, I'm not to have her on her back (including the car seat, bouncy seat, and swing) unless it's absolutely necessary.
About a month ago, I noticed that she had a flat spot on the side of her head. I also noticed that she always looked to the right. When I casually mentioned it to my pediatrician, he said she has torticullis. This means that she has a short neck muscle on the right, and we've got to lengthen it. He gave us exercises and a variety of instructions, and we'll start professional physical therapy if things haven't improved by her next appointment.
Keeping her upright does two things: 1) strengthens the neck muscles, helping her overcome the torticullis, and 2) combats the plagiocephaly.
I, meanwhile, have discovered something for myself that I have always known in my head. Wrapping rocks! I have pouches, I have ring slings, I have mei tais-- but nothing, and I mean nothing, compares to comfort of holding your baby in a long band of cloth. The weight is spread over my entire torso, so I don't feel Charlotte's weight in any one place.
Plus, it's cheap. I was able to make the best carrier in the whole world with five yards of discount jersey-- no sewing required! Just a 20" by 5 yard strip, and the edges don't fray because it's knit.
So I've been able to keep Charlotte upright and looking around in a fairly inexpensive and oh so comfortable way. Surely this helps with her reflux too. And, since she's been so fussy lately (torticullis can cause headaches), I have a way to comfort her while continuing to do the things I need to do.
