Baby DHA???

Daisy β€’ Got my three princes πŸ‘‘ Aaron,Julian and baby Aydan. πŸ‘ΈπŸΎπŸ‘¦πŸΎπŸ‘¦πŸΎπŸ‘ΆπŸ½πŸ’‹
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
