I'm back to add more commentary about the gummy fish and the plain FCLO in case anyone needs help deciding.
I am *really* happy with the plain FCLO! I thought I would hate it, I really did...after all, why would they make all of the flavors if the plain was OK, right?
Well, I have been putting a large crystal of salt on my tongue, squirting the FCLO in the back of my mouth, and then sucking on the salt more. The taste is salty and fishy and as a previous poster said, these things *go together* for me. I don't relish it, but honestly, it's MUCH better than cinnamon CLO, licorice lips FCLO, oslo orange CLO, etc that I've used in the past. My four year old (who loves salt and doesn't really mind CLO in general right now) was very happy with the plain + salt.
As far as the gummy fish...the boys are a bit less enthused today, but they both chose the gummy fish over the liquid. However, the 6yo wanted it in two pieces and the 4yo thought that 5 pieces was more manageable for chewing purposes. They are a bit put off by the gummy texture since it doesn't really feel like any of the 'real foods' we eat. They have commented a lot about how "strong" they are and the 4yo says the cinnamon is a little much for his mouth, but they both love cinnamon and they persevered.
For us, these are two great options and I'm glad to have two such very different choices. (Personally I'll take the liquid because it's over faster...)
