Your baby will begin to realize that the person she's been staring at in the mirror for months is her. Toys with safe mirrors can be very stimulating for your baby. Now is a good time to reinforce her sense of identity by pointing out and naming her body parts while looking in the mirror. You also can play peek-a-boo with her in the mirror to teach her about her reflection.
Make sure your baby's highchair has both a waist belt and a crotch strap to prevent her from sliding down in the chair's seat and strangling. According to the Consumer Product Safety Commission, there have been 19 deaths since 1988 resulting from highchairs. Remember to never leave your baby unattended.
