To me, 10 words sounds to be not alot, though I must admit that my children never shut up. But being an early childhood teacher, I do have a fair bit of experience with children of this age.

This is some info I have collated on speech/language development at 2-3yrs, from when I was working-

General Milestones: Language Development in Toddlers (2-3yrs):

Receptive language (listening):
Can follow 2 instructions using on, under or behind (“stand behind the door”)
Respond to "what?" and "where?" questions (eg-"where's your shoe?“)
Enjoy listening to stories
Point to common objects when they are named (2 year olds)
Name objects based on their description
Knows most parts of the body
String known words together to form short phrases (2-4 word sentences)
Follow instructions that involve an object and action (e.g. roll ball, sit on chair)
Understands 3 prepositions (in, on, under, up, down, out)

Expressive Language (talking):
Recount events that happened throughout the day in simple language
Begin to use adverbs and adjectives (e.g. fast, high, big, soft, etc.)
Use more than fifty words such as "no", "gone", "mine", "teddy“
Listen to stories and name common pictures
Speech used more often than gestures
Talk to themselves or their toys during play
Use some pronouns instead of names (e.g. “me", “mine“)
Begins to put 2 words together (e.g. “mummy car”, “teddy eat” gone”)
Uses a variety of communicative intents (requesting, commenting, protesting, etc)
Answers yes / no questions


How do I know if my child has a language problem?

Does your child have difficulty following instructions. Do you need to repeat instructions often?
Does your child have difficulty constructing sentences or putting words together?
Does your child often start and stop their sentences as they try to get their words out?
Does your child use incorrect grammar no matter how many times you repeat or model the correct sentence?
Is your child taking a long time to develop language or learn new words or phrases?
Does your child communicate in short sentences?
Does not use objects to play.
Does your child understand names of common objects?

I hope this helps. Remember this is just a general guide. Children develope at different paces. Just because you child might bnot have met all of these milestones, doesn't mean there is any issue, it just means he might be taking his time in perfecting his skills. Sometimes a child won't begin to use a skill until the are totally confident in their ability to do so very well.
