I two kids and have been nursing continuously since my daughter was born almost 7 1/2 years ago. My son is now 3. He's been unwell the last few weeks (just normal preschooler stuff but it's just kept coming - ear infections, colds, stomach viruses) so he's been nursing much more often.
My nipples feel like someone took a meat cleaver to them. Never, in over 7 years have I had anything like this. After 7 years I'm going to buy some cream and gel pads tomorrow. I feel slightly ridiculous.
