A frugal life is an easy life!

I grew up in the 1970s with the addage that eating everything in moderation is good.
We never had central heating until into the 1980s, we had ice on the insides of windows on winter mornings, then again we rarely knew anyone with asthma.
We ate everything as kids, worms, dirt, things we had dropped on the floor. We drank corporation pop in the hot summer days, lived for the school holidays on jam butties until teatime.
Allergies were rare in the heady days of my youth, the theory that was the norm then was that if you were not exposed to or fed things, then you could in theory develop allergies to them, much the same as the body is given innoculations and builds a resistance.
Sprog1 was brought up with the same theory during the 1990s, with no ill effects.

So with sprog2 fast approaching the age of solids (how fast does the time go!) an appointment with the health visitor to "advise" us about moving from breast fed to bottle fed then on to solids.

Health visitor lands and lectures us on the dos and don'ts of baby feeding.
It goes without saying that dairy products are no gos, but most things that we eat can be put into a blender and fed in small amounts to sprog2.
Then we were given "advice" that I questioned immediately - asking how if kids are not exposed to certain foods, can they build up a tolerance to them?
The answers were contradictory!

Wheat:
The advice we were given was not to feed weetabix, until after the baby is 12 months old - as babies don't build up resistance, they "instead develop allergies to it!"
So imagine my surprise when a week later I am walking the aisles in Asda, looking at packets of baby rice, I see that recommended baby rice for a 6 month old baby, has wheat proteins added to them!
So who is correct? The government advice via our health visitor or the food company that has been feeding babies for decades, stating that wheat protein benefits our baby from as early as 6 months old?

Honey:
Now I knew this one, babies should not be given honey as it does not go through sterilisation processes, the health visitor confirmed this stating that children under 2 years old should not be given honey.
Today, whilst out shopping, we picked up some Johnson's baby soap - when we got it home it reveals it has an expiry date on it?
Soap that has a shelf life?
As it contains honey!
So who is correct? Official guidelines of the government via our health visitor or Johnson's a company that has been specialising in baby products since well before I was born?

It is not advised to let our baby eat honey, but it is ok to smear her in a product that contains honey?

It is a minefield for parents these days with all this conflicting advice, you pin down a health visitor to give a straight answer and they simply cannot, so what chance do parents of babies have?
