By now, your baby may respond to your presence, your voice, and even your facial expressions by kicking and waving his or her arms. Your baby – who up to this point probably smiled at everyone who said hello – is also beginning to be picky about the company he or she keeps.
In large groups or with unfamiliar people, your baby may need time to get comfortable. Allow for transition time with strangers or when leaving him or her with a sitter.
When your baby is safely in your arms, though, he or she is likely to be interested in interacting with other people – especially noisy, boisterous children because they're more active, more amusing to a baby, and physically less imposing.
