What is the difference between heme and non heme iron?

Does plant iron have the same value as meat iron?
If you are a vegetarian and you’re eating enough plant iron is it as good for you as the iron in meat?
I know the absorption from meat is better, but I’m curious as to whether you NEED the iron from meat, or whether they are one in the same?

I ask mainly as I’m a meat eater, my husband is Vegetarian and we are discussing the pro’s and con’s in regards to meat for our daughter whose 7 months.

I’d like her to consume meat and he’d like us to consider her being vegetarian.

Thanks!

Not paranoid just seeing if anyone here knows as we are having the discussion now. :)
