Hlo I want to ask that my child is 3 months old so which type of flash cards i should use for my baby?

A. Hello good morning !! As baby is just 3 months old they just able to see colours that bright colours. So using flash cards after 6 months is better. You can now make baby learn to see nature while exposing to sunlight,moving objects in room ,talk with expression smile,laugh ,playing hide and seek by hiding face and open with smile,giving colourful rattles,showing swing hanging toys these will help baby in understanding expressions,responding to sounds,voices,expressions...,gross,fine motor skills.
