Aww nakaka-proud talaga yun! Your baby is soaking up everything you're teaching him, and that eye contact at 6 months means he's really connecting with you, that's such a special stage! A few of my mum friends and I were comparing notes, and we all noticed na parang mas engaged ang babies when we sing and do hand gestures kasi nakikita nila yung movement at naririnig nila ang tones, so you're doing amazing by mixing it all together like that. Keep going with the animal sounds and alphabet, baka mag-surprise ka na one day mag-respond siya or mag-imitate, it's so fulfilling! You're not just teaching milestones, you're bonding at the same time.
