WB, I've heard taking echinachea (sp?) is good for boosting immunity re colds etc.
This is what DS took for recent bout of tonsilitis/ear infection (which he always needs ABs for): Hep Sulph 30c for infection & Belladonna 30c for pain. He was better in 24 hours. He's currently being treated "constitutionally" to avoid future attacks. Still a bit of a sceptic about alternative stuff, but imo, anything is worth a shot to avoid ABs/build up immunity.
The homeopath also suggested:
Chamomilla 30c for teething, diarrhoea < Eli, worth a go for DD2?>
Pulsatilla 30c for colds that lead to ear ache & clearing up catarrh/inflammations etc
Aconite 30c for croupy (type) cough. WB???
Belladonna 30c for burning up high temperatures
Was also told that we should let our children be ill (not seriously of course) and dosing them up with Calpol/Neurofen/Medised every time they sneeze suppresses their immunity. Also fever is crucial to the body's success in fighting infections as it wipes out micro-organisms before they proliferate to full-blown illness. She accordingly told me only to give DS calpol etc if his temperature rose over 40c. Interesting stuff and to me, quite sensible.
Eli, can you just stuff DD2 with bananas? Add an extra scoop of formula to bottles? Fwiw, my DD2 is also very long and lean. Can't tell you percentiles as I haven't had her weighed since she was about 8 weeks. Definitely both future supermodels though Let me know if you need a hand with anything, I can be in your manor in no time.
