Very low iron with a toddler.

[Misschief]

My 20 month old son was diagnosed with severe anemia at 16 months old. He was licking everything and anything he got his hands on. His iron level was only 7 when normally it should be above 11 (or so I was told).
He had to have an iron supplement for 3 months and then we did another bloodtest which showed that his iron level was ok.
Now he's been off the iron for 2 months and he's started to lick everything again. He never really stopped, but its become worse in the last 2 weeks.
He needs to get another bloodtest in 2 weeks time, but Im really worried.

When he gets out of bed in the morning, he starts with a glass of milo mixed with water. Then an hour later he gets a big bowl of weetbix with 2 pieces of fresh fruit. I need to add that he doesn't get milk with his Weetbix. The juice of the fruit makes it soggy enough.
For snack he gets a bit more fruit, or some rice crackers with extra iron (the Heinz Baby ones).

For lunch he gets wholemeal bread with cheese, Vegemite or this super expensive " 100% all natural" almond spread ($6,- for a small jar in the healthfood section at Woolies). I was told by the dietitian that this has a lot of iron in it.
He also gets a small cup of yoghurt when he goes to daycare twice a week.

Afternoon tea is some plain Jatz crackers.

For dinner it's fresh veggies, potatoes and meat (pork, fish and steak twice a week.) Once a week he gets baked beans with eggs for dinner.

I was told Chia seeds and Spirulina had lots of iron in it. But then some dietitian said that you need to eat a kilo of Chia seeds to get the same amount of iron similar to a normal sized piece of steak.

So how else can I get more iron in him without using the supplement?
