Advanced skills of a baby

Hello, mommies! I'm just wondering lang po kung "ANO IBIG SABIHIN PAG ANG BABY MO AY NASA ADVANCED SKILLS NG MONTHLY MILESTONE TRACKER?" Any idea or advice? My baby seems to be advanced. When he was 1 month old he can already gurle smile and laugh and lift his head during tummy time. Now he is 2 months old and can already roll over when tummy time, knowing the fact that the skill is for a 3-month old (advanced skill) I'm just so curious. Thanks for sharing your ideas mommies. God bless us and pur little ones. ❤️#advicepls #advancedskills
