For Baby's Brain Development

My ob recommend fishoil. Not sure kung anung brand. Nung nagtanong kc ako sknya about sa iniinom ko na lasang isda sabi nya fishoil yan for babys brain developmemt pampatalino daw. So far ok namn si baby ko lahat ng milestone nahit nya then at her age dami na nyang alam na words at madali cyang maka pick up maybe because purebreastfeed din cya. Shes 18 months old na.
