Trembling while falling asleep

[kismetbaby]

Anyone else notice this?

I'm not urgently concerned about this, but I have been noticing that as my 5.5. month old LO falls asleep (which he always does nursing) he often gets these trembles. It seems to happen when he is slipping into real sleep--transitioning from sleepy nursing into deeper sleep when I can extract my nipple. Sometimes its just his head twitching and sometimes its his whole upper body trembling. It only last maybe 5-15 seconds.

Should I be worried or is this normal?

my baby does this too. he's now 6.5 mo, and it seems to be slowing down. from posting on MDC, my reading elsewhere and talking with the pediatrician, it seems to be "normal." the major criteria is if you can make it stop. for example, adjust him to a new position and see if it stops his head from shaking. or if it's the arms, put your hand on his shaking arm and try to make the shaking stop. if you can, it's normal. so they say!

also i've read that it ends around 7 months. as i said, we are 2 weeks away from 7 months, and it is happening less often and there's less shaking when it does happen.

now, if i may ask you a question, did you have many ultrasounds when you were pregnant? i did, b/c i was "high risk" (age 41) and my doctors' group was paranoid. i have wondered in passing if this might have "caused" the shaking. but if you tell me that you did NOT have a lot of ultrasounds, that blows that theory.

just curious. thanks!

I only had two u/s. . .at 12 weeks and at 20 weeks. Completely uncomplicated pregnancy and birth.

He doesn't tremble every time, so I wonder if it has to do with how quickly or not he falls asleep? Or how sleepy he was to begin with? I know sometimes when I doze off or get awakened in that place btw wake and sleep I "startle". . .so I thought maybe it was like this.

I usually hold his head or arms when he does this, but I haven't tried changing his position (cuz I don't want to wake him). I can definitely hold his arm still though.

I believe normal. My ds1 did it, and I was a *bit* worried and remember posting the same question to a message board then! He grew out of it, about in the time frame the pp mentioned.
