I did. Now we sometimes get 13. But yeah, it was 10 at night + 2 hr nap for a looooong time.
Honestly at 2 (26 mths now) he seems to have become seriously high sleep needs, getting OT at the drop of a hat when he used to run around on 12 hrs. So things can change at the drop of a hat!
Your LOs development sounds spot on to me. F is just finally interested in building towers, although smashing them is much more fun for him. He loves pushing things too. He has no patience for fine motor skills, often getting very frustrated and giving up. He's all about the gross motor. ALL kids eat the inedibles I think, really, but if you have a concern about pica then you may want to get his iron levels checked just to be sure. Have you talked to your doc about your concerns?
Speech development comes in fits and starts, we had nothing (nearly 0!) at 20 mths and then he got ear tubes and now he's almost having real conversations. Still a lot of gibberish though. So I think your LO is doing fine :-)
Sounds like he might have hit a growth spurt or developmental leap or was just extra tired that day. We got these blips too at that age, and then he'd go back to 'normal'.
I've analyzed the exact same question, pretty much every day since he was born lol I still haven't come to any conclusions, and the kid is awesome and thrives in every way, at his own rate. So best not to overthink sometimes ;-)
