Omega 3's for kids/toddlers (breastfeeding, pregnancy, children, natural)

[miasmommy]

Through pregnancy I replaced my Walmart Omega 3's (not the best) with a DHA suppliment derived from plant sources which is also mercury free. Now that I am not breastfeeding as often and my child and hubby are not big fans of fish, I'd like to supplement my daughter. She gets flax seed and eggs very often but I'd like to know if any of you know of a good high potency omega 3 for toddlers/adults which is mercury free AND a fish source.

We give our kids Nordic Naturals Children's DHA. I believe we buy it at Vitamin Cottage.
