Too tight?

In the last couple of weeks, R has thrown up a handful of times right after mealtime.  Not alot, just a little, like his tummy got too full from eating too much.  I'm starting to wonder if his cast is too tight.  A couple of weeks ago, he started getting pressure sores on his lower back, just above his right hip.  We called Shriner's and they told us to apply some more moleskin, and we did and it cleared up in a couple of days.  But again, this cast just seems like it might be getting too tight.  So I also wonder if we will take it off early, and he'll get more time without his cast on again.  That wouldn't be all bad. :)

I just hope he isn't too uncomfortable.  It's hard to know when to take it off.  When is it too tight?

The PT came today.  He's doing AMAZING.  He's so close to getting up without holding on to anything, he's talking more and more (he's not behind AT ALL in that area).  We're going to space his PT appointments further apart (YES!) because he's doing so well.  The only thing I am worried about in regards to his motor development, is that he isn't turning his neck as far as he used to.  When he turns his head far to either side, his chin runs into the part of the cast that goes over his shoulders, and he seems to be convinced that he can't turn it well anymore.  This just started this week.  Maybe he's stiff (from the cast)? Who knows.  But he won't look at things to the side or behind his shoulder without turning his whole body. 

I"m so proud of him.  He works really hard to be able to do so many things, like getting up and off of chairs, go up and down stairs, stand up, bend over, etc.  He doesn't ever complain about these things either.  I think he likes some of these challenges.  Such a boy.
