We just started the orange CLO, and I gotta tell you the fermented fishy smell is SO prevalent, that I just can't imagine that anything would mask the smell. It is STRONG and it lingers on everything it touches. Me and DH shoot it and butter oil mixed in cranberry or pomegranate juice, and DS takes it in the little syringe they give you and chases it with the juice. He's 3 and it's a two man operation: DH sits DS on his lap and holds his nose, I squirt the CLO and DS holds his chaser. The taste is not so bad, especially with the cranberry juice, but the smell.....
For the first few days, DS really protested taking it, crying, working himself up, getting really upset. We explained that we wanted to try to fix the holes in his teeth and everyone in the house had to take it every night from now on. It's been about a week and he still doesn't like it, but he tolerates it, and thinks it funny when me and DH exaggerate how yucky it is.
