5 months old

Okay, so sa experience ko with my friends' babies, some are really vocal talkers na from 3 months pa lang cooing like crazy, pero iba naman are quieter at medyo late bloomers talaga sa sounds, so hindi lang yan automatic sign ng something wrong. The fact na makaka eye contact siya and tumitingin when you talk to her is actually really good, kasi yan ang mas important developmental milestone at that age, honestly! That said, since your gut is telling you something feels off with the cooing, I'd still suggest mentioning it sa doctor during your next checkup, just para peace of mind lang and they can assess kung normal lang spacing ng development or if may need to monitor, walang mawawala, di ba? Keep doing what you're doing with the talking and interaction, kasi that's what matters most
