Sometimes the best stimulation is no stimulation. Be sure you are reading your infant’s mood to determine what activity is best:
An interactive activity is best when your baby is seeking you out with her eyes or reaching with her hands, or is generally alert and ready to go!
It is time for a solo activity if your baby is not tired or ready for sleep but is fussy or perhaps has just been highly stimulated, for example, by being outdoors or she has had a visitor. A quiet solo activity such as looking at her paper plate faces may be just what she needs.
Perhaps, however, it is time to lower the lights, block out general noises, and just sit together quietly. You can sing a quiet song, just rock, maybe read a book, but generally keep the activity level low.
