Fish oil recommendations

[angpat]

please could you give me recommendations for fish oil for omega 3/dha to help with sensory issues/hyperactivity.
I have been recommended Nordic naturals and also wild Alaskan summit fish oil due to its high concentration.
also wanted to ask would it be okay to add to evening /morning milk at luke warm temp?

thank you!

How old is your child because if they have sensory issues they are likely to refuse fish oils. I've tried all kinds of gummies (my daughter won't swallow capsules) and anything with omega 3 is rejected which gets expensive!
