Baby DHA???

Daisy • Got my three princes 👑 Aaron,Julian and baby Aydan. 👸🏾👦🏾👦🏾👶🏽💋
Have any of you lovely mothers heard of this??
I want my son to be as healthy as possible!!
Have any of you used this before??
And if you have when did you start giving it to your babies.
I was hoping I can put it in his milk when he's an infant can anyone give me advice on it or is it's safe
