I think people should look seriously into iron needs and do so objectively. I find it unlikely that you or your children are getting the rda through diet. It might be wise to consider topping up.
Women need 14-18 mg per day, depending on which countries gov advice you follow. A child of 7-12 months need 11. Now as someone who has low iron levels, but is not affected by it in day to day life (I found out after being rejected for giving blood) i have tried to construct a diet which hits 14mg a day, everyday. I think most people would be surprised te dedication that takes. Plant food does not cut it- the only way to guarentee hitting this everyday is to include fortified cereal (mn sin I believe- isn't homemade next to nothing iron the alternative de jour for this sugary kelloggs controlled nightmare) eggs, and red meat. Spinach, red pepper, have v small amounts in them, making them a waste of food in your eating: iron ratio.
The veggie options which are passable are baked beans, and figs.
Yet There is still huge contraversy and no blanket opinionon how well your body absorbs the iron from food (it's commonly in medical literature that te iron in spinach is next to useless)
a baby need just 3mg less than that, and they will eat far far less in terms of calories and portions. I actually think most people kid themselves if they believe they can get the rdas for vitamins and minerals they should have from diet alone.
However, there is Also a decent argument that you do not need the rdas and there is little scientific evidence to prove they're correct. That however is a different argument to people saying they get all their iron from their diet.
