Hi, Mommy. In my opinion, always have a playful tone and way towards your baby. Mas interested po kasi sila in something na palaro ang kilos, at the same time, natututo at nagiging creative po sila. Be patient nga lang po if madalas ayaw niya sundin or matulin mawala interest niya. Sa playpen naman po, maganda po kasi 'yan to maintain the space na lalaruan niya. Let him/her play whatever things he/she wants. Creativity po ang nade-develop sa kaniya and brain processing skill. :)
