She's better now (symptoms were upper respiratory infection (viral) with high fevers - just since yesterday but she's very chesty and pale and wan looking and gets tired very easily and generally seems to have lower muscle strength (was really going for it with the walker but can now barely drag herself to standing). She's now having 3-4 breast feeds in a 24hr period (was 2 + solids) and is refusing all solids. This has been going on since last sunday. Does this sound about right and when should I be worried?
