if you want, you can assist your baby to help. i started to assist my 2nd baby at 5months. dahil nakakagapang na ang 1st born ko at 3months. once i assisted or teach her, nameet nia ang milestones before mag 1yo. 5months - pinaupo ko si baby sa inflatable seat with back support. assisted to roll over. 6-7months- roll over on her own and crawl (fast crawler). 8-9 months - sit on her own. can stand on her own. 10-11months - walk on her own.
