Thanks for the kind thoughts everyone Ethan seem much better today and so do I now. *sigh of relief
I was so worried that it would be dangerous for him to get the pox so young but the spots finished coming out yesterday and they are dried up today, his fever has reduced significanlty and he woke up all smiles - I actually dont know how long he was awake for but I woke up at 7am (body clock) and he was happily playing in his basinette beside me, full of smiles. He didnt lose his apetite (which usually happens with chicken pox), and only has a very slight cough so I am confident we are over the worst of it now

Thanks for all that info TMTM, that is sort of what my GP was telling me - kind of... basically saying you wont know what he's allergic to without trying it and that DH's reactions to food are not life threatening so it's not likely that Ethan's would be either and that introducing them early may help him build a tollerance to it. But I just really wanted to continue breastfeeding but was just plain exhausted from feeding so regularly, especially with all the illness and growth spurts and teething etc not allowing me to get sleep at night. And so far so good... he went to bed at 9pm last night (the last few nights he's been waking at 10 and not going back down till 11 or 12 ) but he slept until 3:30, stirred at 6am but resettled himself then I woke up at 7 and he was awake. so it seems to be helping.
He has potato and pumpkin at lunch time and he loves it, I also find that he skips a feed in the afternoon which means by his next feed I have heaps of milk so he just has a longer feed then is all set till bed time, so I can get dinner made and have time to relax with him and DH until his next feed.

Ray - I agree with TMTM I dont think you can overfeed a baby. Babies eat what they need! My fiends have a baby that almost doubled in size just from switching to formula, she was in size 1 at 10 months. But she's the happiest baby I know, never grizzles always smiles and is just a beautiful baby girl! THAT is what matters, it's much better they have reserves than be underweight or being one of those babies that rejects food and needs to be drip fed... That would break my heart!
He looks like a beautiful happy boy to me so I wouldnt be too concerned. Once he gets mobile and taller he'll be leaner anyway
