According to What to Expect the First Year:
By ten months, your baby

…should be able to:
-stand holding on to someone or something CHECK (this is his favorite thing to do)
-pull up to a standing position from sitting CHECK
-object if you try to take a toy away NO- he’s good natured and doesn’t object to much
-say “mama” or “dada” indiscriminately CHECK
-play peekaboo CHECK
-exchange back-and-forth gestures with you CHECK
…will probably be able to:
-get into a sitting position from stomach NO (he did it once but seems to have forgotten how)
-play patty-cake (clap hands) or wave bye-bye CHECK
-pick up tiny object with any part of thumb and finger CHECK
-walk holding on to furniture CHECK
-understand “no” (but not always obey it) CHECK

…may possibly be able to:-stand alone momentarily
-say “dada” or “mama” discriminately NO (but I think he said AT once when he saw Sam, our cat)
-point to something to get needs met NO
…may even be able to:

-indicate wants in ways other than crying CHECK (he smacks his lips when he’s hungry)
-“play ball” (roll a ball back to you) NO (but he’s thrown it to play “fetch” once or twice)
-drink from a cup independently CHECK (but water gets everywhere! Does it count if he doesn’t do it neatly?)
-pick up a tiny object neatly with tips of thumb and forefinger CHECK
-stand alone well NO (but he can do it for a moment)
-use immature jargoning (gibberish that sounds as if baby is talking in a made-up foreign language) NO (but he does repeat sounds like dadadadada in a way that sounds like he’s trying to have a conversation)
-say one word other than “mama” or “dada” NO (unless he really did say AT for “cat”)
-respond to a one-step command with gestures (“Give that to me”- with hand out) CHECK
-walk well NO
