Hi po! I'm not familiar with "Tinybuds after shot", is this a product or supplement na inaalok sa inyo after vaccination? Better to check with your baby's pediatrician first because anything we give newborns kailangan talaga ng doctor's approval, especially right after shots when their immune system is doing a lot. Let me know what it is exactly and maybe I can help more, or kung may nagamit na ng iba sa circle ko baka may idea din sila!
