Ouch, FGS Seem to remember my DSM having similar knee problems, v painful, in the end she had minor keyhole surgery and is now back to climbing hills and skiing - hope yours is easy to fix, whens the MRI?
I hear you both re back, promise, see osteopath from time to time as have dodgy back anyway (family trait, sister and mother too) which ironically only ever feels really fine when pg. Shame I can't use that remedy again
As for eating...I agree with FGS; not worth the battles, though OH so easy to fall into some days. dd1 is pretty good, but far more limited in what she'll eat than she used to be.
If veggies are an issue, but she likes a) DVDs and b) raw veggies, you could try what I do - every evening I give the dds a plate of assorted raw veggies (cucumber, toms, peppers, carrots, even bean or two, or a sprig of raw broccoli sometimes) in front of a DVD for half an hour. BEFORE supper. They are usually hungry at around this time, so nibble away whilst distracted, and I don't stress about veggies so much at mealtimes.
Unusually, this was actually a tip from my DSM who is not known for helpful advice re LOs - this one works a treat
