Think I'll see how it goes - if it continues I'll ring the MW. Yes, I prob did too much. I'm feeling much strong now thanks, so I think I got a bit ambitious!
DS is thriving, he had his tongue tie snipped on Thursday and has been feeding much better since then, and going longer between feeds so I'm getting a lot more rest (and less painful feeding - right nork now doesn't hurt at all, still working on the left!)
Thanks all
