Hay, first time mom struggles talaga, pero honestly at 5 months kailangan mo talaga makonsulta sa pedia kasi mahirap i-self-diagnose ang ubo ng ganyan na edad, lalo na kung matigas, pwedeng something na kailangan ng proper check. A few of us moms tried home remedies like steam (kahit hawakan lang baby mo habang nag-shower ka) or elevating the head while sleeping, pero really, don't skip the doctor visit para sure na okay ang baby mo at walang worry ka, ok? Hugs, first time parenting is tough pero gagaan yan!
