RE: anyone else feel this way?
The tingling sensation you are feeling is the letdown reflex. I felt it that way too. Some women feel nothing though, so everyone's experience is different. And when you breastfeed (or pump), your body produces oxytocin, which causes the uterus to contract. It really is very normal to feel those things, it means your body is working just like it is supposed to. :)
I would also second the suggestion to see another LC. I had to see 3 to find one that could really help me. To be honest, it sounds like she is giving you some poor advice. There are lots of ways to increase supply if that is the issue. Are you supplementing with formula also or exclusively pumping? If you are EP, then I really doubt you have a supply issue. It may be hard to get a 3 month old back to the breast, but not impossible with the help of a GOOD LC who is experienced with that sort of thing.
I would also recommend La Leche League as a terrific resource for ou. I was at a meeting today where there was a mom with a 2 month old and she was exclusively pumping. They are going to try and work with her to get the baby back to the breast.
