The pint-sized vegetarian

I have a seven year old daughter who is a vegetarian.
You may think she is going through a temperamental phase or trying to assert her authority over the family with doe eyes and shouts of ’but that’s a piggy-wiggy!’ I would have to agree with you, had I not seen the catalyst.
There were already some signs of what was to come, when, after watching ‘Finding Nemo,’ she proudly announced she would no longer be eating fish.
Then we went on a camping trip last summer and whilst eating her favourite breakfast of bacon sandwich with lashings of ketchup, she asked where bacon came from. We tried to use euphemisms (i.e. lie) but there was no getting round it, she was eating piggy-wiggy, just like the one in the adjoining field, whom she had named that very morning.
From then on she stopped eating any meat, all the favourites gone one by one, as she realised which animal her tea came from.
As a dutiful mum I, of course, went along with her choice, I can‘t imagine trying to force her to eat something and she is genuinely upset by the thought of animals being killed for us to eat them.
So as a family we now hardly ever eat meat. We were never great meat eaters anyway but we actively exclude it from our diet, rather than chicken we have Quorn, instead of mince beef we have lentils, etc.
There is a small problem on the rare occasion when we do have it. For a treat on my husbands recent birthday, we decided to have steak, but we had to wait until the kids were in bed, as we couldn’t take the upset and the doe eyes!
It isn’t easy trying to feed two young children, ensuring they get all the vitamins and minerals etc. they need. As they don’t like anything too spicy, the food we like is out, but the temptation to just steam their veg, although an easy option, is not appealing.
I also have the added problem that my four year old will, pretty much, only eat meat, or Marmite sandwiches, but that is another story.
As a devoted wife and mother, providing meat free meals: tasty for us, bland for others (and a burger for my son), I was surprised as I looked for recipes on the internet, and researched the subject further, by the shocking amount of animal bi-products in ordinary everyday products.
So we are merrily going down the route of feeling good because no animals are being harmed so we can eat, but there are products with animal content that will just make your jaw drop!
I am going to do a little research project to find out what contains little bits of ground up animals and what euphemisms they use to disguise it.
There are some obvious things to look at, like gelatin (ground up animal bones), whale blubber (used in lipstick), but there are some things that are unbelievable, like rennet (newly slaughtered calf stomach lining, used in the cheese making process) or ambergris (whale bile, used to make perfume.)
If you know of any animal parts hiding away in products, please let me know.
