close,open??

Usually around 8-10 months, mama, when they start understanding the "open close" game, though some babies catch on earlier or later pa, honestly, every baby's different! One of my mum friends' baby was doing it consistently by 9 months, pero ang aking firstborn took until 11 months, which is totally normal din. At this age they're learning hand coordination and following simple gestures, so keep playing with them and they'll get there, don't worry, wala nang baby na napunta sa kindergarten na hindi marunong magbukas at magsara ng kamay, hehe!
