We're new to pumping (about 3 weeks), using a Ping on a 4 1/2 yr old. We are using contact-detach(sure T's). We have twice put sites on his love handle area (lower back), and each time he has complained that if he lays on his back he can feel the needle. My husband thinks we can just use the 4 areas on the stomach for now, upper and lower stomach, each side. I personally think that's not enough rotation, and don't want to get our son in the habit of only using 1 area. Arms are for the dexcom.. we haven't tried legs at all. Do you think the stomach alone is enough? Would you continue to use the bum area (maybe a fluke with feeling the needle?) Should we try legs? Ideas and thoughts welcome.
