My dd lost her appdtite for solids recently. After a week she was a bit more interested, then a bit more and a bit more. Four weeks on and she eats more than ever. Be patient and keep offering her food and her milk feeds.
My dd went through the same stage quite recently. for almost 2 weeks she never ate and refused everything and i was really beginning to panic. gradually she started to eat again and now shes back to normal. as long as she is still taking her milk she will be fine!
