COMMUNICATION
Babbles become primitive communications - you may hear lots of single syllable utterances that sound like “da,” “ma,” “ba,” “ga.” Babies at this age can echo our sounds so you may hear things that sound like uh oh, hi, ooh - babies are clever and may only say them once or twice, then stow them on the back burner for later use.
WAVING, CLAPPING, AND RECOGNITION
Waving emerges in many forms - the “classic” wave, the “Italian” (palm facing baby), and the “too cool” (arm down at side, fingers touching palm). Clapping may become common if you routinely applaud in your household. Otherwise, it is not necessarily an intuitive accomplishment! True recognition of friends and family is obvious: baby reacts consistently to consistent figures - including pets.
SITTING AND CRAWLING
Sitting for long periods is common, followed by floor exercises. Typically, babies start to “combat crawl” (with arms alone), followed by many variations of crawling - including pushing with one or two legs, rolling and twisting, getting up on all fours, scooting on buttocks while sitting, etc. Many, but not all babies accomplish mastering true crawling. Some seem to pop up to standing, almost bypassing crawling altogether. Once baby is on the go, exploration of everything in his path is a must - so providing a space for movement, as well as some soft obstacles to crawl over and around, is a good idea.
