Hello...I am new here and want to know about babies activities at 7 month...as my baby going to complete 7month on Sunday....

His activities roll in both direction
Crawl
Reaches for any objects
When I make weird or funny face look at me and laugh or smile(I want to know is laughing is necessary on tickle or smile is ok.... Or no reaction ...actually my baby didn't laugh on tickle on feet or tummy sometime...when sometime I flow bubble on any part then laugh and sometime not..so want to know is ok?)
Turn to rattle sound or my sound or my husband sound but when try to reaches for any object or engage with toys then can't is it ok...bcoz at that I call so many times...
Fear of cooker wristle
Move eyes to moving objects
Make sounds like aaaaaaaaa sometime baba amma type is this babble cooing sounds ?
Tap on objects or on my self with hands
Sometime smile while peekaboo game sometime only look on my hands
Hold toy with both hands and shake not transfer it from hand to hand ..when they do...
Reaction on. Sound that I asked above is ok na ??
