This is definitely a helpful thread... we had mixed feelings about whether to check/not check and how frequently... she's on a very low dose of Lantus right now (2 units) and typically her 2am check # is frequently between 120-160 if she goes to bed under 180. She usually wakes (I say 'usually' but by that I mean 'lately' lol it sometimes changes week to week you know how it is) between 80-120. If that stays consistent along with our meals I do take a night off.. but I might just reconsider. Right now we have a relatively controlled environment since she's in honeymoon and on lantus and is 3 - so she eats like 6 different foods ever (yep, I've got that child). But I know as she grows and changes her diabetes will too... hard to hear but helpful info here.
