Your ninth month, day by day
Days 241 to 270: the 9-month list, looking when you call, arms up, goodbyes, peekaboo, the pincer, finger foods, cups, crawling and pulling up, walkers, pointing, shoes, nights, the safety walk, bye-bye and pat-a-cake, vaccines, the 9-month visit, and nine months, with one new thing to try every day.
Every note draws on the 7 to 12 months guide and cites its sources. Babies don’t keep calendars: read each day as “around now”, and let your pediatrician’s read of your baby beat any note.

The screening preview, looking when you call, arms up, reacting when you leave, peekaboo, the pincer, and words before words.
