Mm. I use an Animas pump. My doc wanted me to go with a different one (the Deltec Cozmo) and thought I would because it was more techie, but I went with the Animas because I thought it would be more liveable. It probably is (more liveable)... but I can't say I can really recommend it technology wise. It might have been better for me to get the other one.
Anyways, I'm not sure that the Medtronic and Animas are not similar in size. Do you have the Revel? But maybe they are, because I don't get uniboob or irritation wearing it under the arm... Well, I wear it a little forward of under the arm. I stick it under the bra strap, so really it's in front.
I hear you about trying to wear the pump on the inside of the leg. My mom made me a little pocket that I pin on the inside of waistbands sometimes. That works well enough for me (although it's a little troublesome to whip the thing in and out).
I don't see the pump in pic #2, but on the other hand you do look a "little bit pregnant." (Haha, maybe a person can be a "little bit pregnant" after all - with an insulin pump!) Have you thought about wearing it more to the side? Near the hollow of the hip bone? Also, I will show off my pump, like do a half-tuck where it is if it's gonna make my top lumpy.
Outfit #1 is gorgeous btw!
Oh, I just thought of something... I actually wear the "Calf Thing" too, up just past my knee. I find it 1) doesn't slide down as much 2) doesn't make it impossible to walk and 3) makes it easier to get to the pump.
If I don't put the pump in my bra, I will note I don't tuck my shirt generally. I also like to wear it up top, because I find it falls out of pockets all the time.
My oldest friend, diabetic of almost 35 years now, has never gone on the pump because it really annoyed her. She's a more classic dresser, which I would say you are too. I, of course, am a crazy dresser... My swingy sweaters and oversized boxy tops may make the problems less noticeable to me.
How long have you been on an insulin pump, Freckles? Have you just been living with the irritating factors a long time?
