Hi there,
It actually sounds like he is eating really well! Definitely on a par (if not better) than my toddler.
I think it's great that you will be able to see a dietitian to get some more insight and ideas on what else to add, what supplements etc. Might as well take advantage of all the help you can.
In the meantime, I wouldn't worry at all and just continue on how you are. We never saw a dietician, but won't count it out for the future.
Not a lot of advice, sorry, but hope this helps a bit.
