we are another "no additives" household.
dd1, like saintlydame's ds, cannot tolerate anything artificial at all. including flavourings, colourings and preservatives. dd2 looks like she shares a gut profile with dd1, but then she's never had the stuff as I refuse to cater separately for the apir of them.
and yes, that incudes suncream. (loads of the high street suncreams have wheat products or milk products in anyway, neither of which dd1 can have)
we managed 3 weeks in Australia (in Brisbane) last summer, without suncream. we use loose cotton clothing, hats with flaps, etc. both girls are very pale skinned (as am I).
the only time dd1 has ever burned is when she was at nursery, when she had suncream on - the idiots thought that meant she could be out all afternoon
we have neutral shampoos/soaps/washing up liquid/washing machine soap - you name it, we have a "chemical free" version. dd1 literally reacts to anyhting.
I'm in the "why would you take the risk" camp. there are no long term studies proving the safety of sweetnersparabens etc. why on eearth would you consume/rub in this stuff when there are alternatives?
