My son (4) just started on the pump (Ping) last Thur. We did his second site change yesterday before dinner. Both when I did the "fill cannula" and when I bolused before he started eating, he complained that it hurt. However, at the end of dinner when I gave him the rest of his insulin, he did not complain. (we split boluses because he's 4 and not always sure how much he will eat.) I called our pump trainer and she said it could be hitting a nerve and that if it keeps hurting to change the site and of course change it if his numbers were high 2-3 hours after dinner. His numbers were good after dinner and bedtime - so I think the infusion set is in OK.
Then at 1 am when I was checking and had to do a correction (we are probably going to have to adjust evening basal), he stirred in his sleep upon insulin delivery - so I think it must actually hurt? He complained this morning with both breakfast boluses. Only for a minute, but he did not want to get the site changed as he is pretty scared of the site change process - I think he is just freaked by the new equipment since there is so much of it. It is the only thing he doesn't love about the pump.
So if the site is working, I am tempted to not change it. What do you all think? And I can't figure out why it hurt when I did the fill cannula - he's not supposed to get any insulin then, right?
