Mine was like that.
In development, very few kids are early, on time, or late with EVERYTHING. At 1 my son wasn't walking yet, was still babbling, wasn't using utensils (much less drawing!... the closest we got was when I cut his hair, he'd smear shaving cream all over the mirror.
By 1.5 he had a few words (most of his communication was done with body language), was just figuring out the walking thing (wasn't really "good" at walking until 2, and would revert to crawling, because it was faster), etc. We just enjoyed him. He was having a blast figuring out the world, he just did it at his own pace. He wasn't MISSING milestones, he was just at the latest edge for many of them, but early on others (like smiling and laughing the first week, and dead on with others like rolling over).
Even though it seemed like he was "behind" on language & movement...By 3 he was reading fluently at a 1st/2nd grade level (he started reading at 2.5), typing on the computer (no hand strength for writing) and was in CONSTANT motion... Jumping/flying off of furniture. We had to put him in gymnastics/swimming/soccer & buy a puppy just so he could burn off the energy that was radiating off of him. (We also had the "terrible three's" at our house. Thankfully things calmed down when he hit 4).
Kids don't all develop at the same rate/time... that's why there's a "range". We weren't concerned with him, because he was within the range, and we didn't do any intervention stuff, because we weren't concerned. (Now we have autistic & developmentally disabled kids in our family, so we also had a really good "meter" to compare against. He wasn't exhibiting concerning symptoms... like not making eye contact, mewing, etc... so even though he was "behind" his peer group, no worries. And as time told, did he ever "catch up"!! Oy. An early reader is a nightmare, btw).
Some kids also just have strong likes and dislikes. My son has ALWAYS disliked drawing/painting (and I'm an artist, so go figure), and is as stubborn as all get out. Prodding in any direction equals an immediate dig in the heels and stop. He was fantastic with chopsticks, until someone "handed" chopsticks to him, instead of letting him pick his own. This was also around age 3. He hasn't used chopsticks since. The things he loves, you can't keep him from doing, and the things he dislikes... you can only get him to do via careful manipulation.
Mom-instincts are good... if you "feel" something is wrong... ALWAYS trust your gut, but don't get too wrapped up in what other kids are doing & or capable of... because that is a really fluid set of criteria.
:) best,
