Your baby’s 40th week
Your little one will become increasingly mobile. Now he’ll have perfected his crawling abilities and will be on the go whenever he’s placed on the floor. He’ll alternate hand, then knee, first one side, then the other. This new, more mature motion, will allow him to balance on one hand while reaching for an object with the other.
He’s also learned how to move from a crawling position to a sitting position, enabling him to fully inspect and enjoy the toy he’s grasped. You’ll find that he’ll also sit frequently just to rest his tired limbs.
He’ll also learn to crawl up stairs and will delight in displaying his newfound abilities, whenever the opportunity presents itself. Unfortunately, he has not yet learned how to go back down the stairs once he’s climbed up. Take care to securely place a gate at both the top and bottom of all sets of stairs to safeguard against any accidental falls.
Your baby’s 41st week
New sounds continue to flow from of your little one’s mouth each day. She’ll test her ability to make these noises by babbling streams of random vowel sounds. Very soon, these strings of seeming meaningless sounds will take shape as individual "words" with very clear definitions. In addition to these sounds, she’ll also begin to imitate non-verbal noises such as coughs and sneezes. She’ll discover that certain sounds (such as a cough) will cause you to turn and check on her. She may delight in making these sounds simply to attract your attention.
Her now well-developed pincer grasp will enable her to pick up very small items. No speck of dust is safe from curious little fingers as she crawls about the floor. Be sure to sweep and vacuum frequently and watch carefully for dangerous items that may have fallen within her reach.
