I’ve been using Youbaby since 4 Years ago with my first born. Kahak akan keluar ikut najis baby or dia akan muntah kahak. A lot. Now I’m with my second born, 1 months old. Guna youbaby sebab dia ada blocked nose, sama juga keluar ikut muntah & najis. Helped a lot! TW: Baby snot & phlegm. Disclaimer: My own experienced with youbaby. I’m not an agent.
