Oo normal yan sa 2-3 months, sis! A few of us went through this phase and honestly it was so nerve-wracking, pero it's usually just her way of talking or exploring her voice, hindi lagi dahil sa problema. That said, if she's screaming nang pareho every time or you notice she's not feeding well, sleeping poorly, or may ibang signs na off, better check with your pedia just para peace of mind, lalo na first time mom ka talaga. Mahirap mag-worry, gets ko!
