Mine said "no" to everything, indiscriminately. I'd offer water, she'd say "no" and reach for it desperately

Next came the "yes" phase; same thing; everything was yes and she would, for example, reject the banana after I peeled it. Now at almost 19 months she is getting more consistent but waffles between too much yes and too much no - I guess to keep me on my toes lol.
FWIW, she didnt point until 18 months, wasn't interested in body parts (so couldn't identify any) until after 18 months and just now is using mommy, daddy, "gamma" and "gampa" consistently for the right people. She's been doing animal sounds for months now and can do at least 15 different ones (or say the animal's name). For a long time she spoke way better animal than English. When we were at the dr's office around 16 months I asked what they were looking for in terms of language at 18 months. She said 12 attempted words - doesn't have to be fully clear or too consistent, just that she is trying to communicate and can make a variet of sounds.
Your toddler sounds perfectly normal. They all figure things out differently at different times based on what interests them and what their personality is like. I'm not an expert but he sounds just perfect: very similar to both my daughter and my niece at that age.
