Hai good evening !! The best way is to engage baby in activities arranging toys,blocks colour wise,shape wise ,changing toys ,blocks or any things into one basket or bag to other ,choose colourful blocks,toys which makes kids interesting to know the colours.
Give finger foods boiled veggies,ripen fruits into hands ,poha,mur mure they will pick and eat .
  Playing with utensils ,touching different textures from soft toys ,flash cards to flours,play dough with atta dough ,playing with water bath toys ,picking things,counting ,sorting things.
  But be careful there should not be any small,sharp objects which kids might put in mouth cause choking always be with baby while you engage  baby in activities.
