Thank you Julie, and you too Tiger Lily. Yes, she does use the pen you
both have pretty much covered what we are already doing. Rather than
large bubbles that can be moved easily, she seems to get lots of little
bubbles all the way up the side. We do a lot of beating up on the pen,
either by  using a pencil or flicking it with a finger to get them near
the top so they will come out with a 2 unit primer shot into the air. We
had to throw one pen out because we just had too many bubbles to deal with.

Unfortunately, the local diabetes center had no useful advice. I will
try calling the company that makes the lantus pens to see if they have
any advice. Or even if a little air bubble subcutaneous is at all harmful.

Thanks  again.
