My son is 15 months can walk, but only 6 teeth, doesn’t talk yet but can understand commands like ‘put it back’ or ‘let’s go’ etc. he sleeps 7-7 it took a year of sleepless nights to get there 🙏 but he only does one hour nap at a 10.30 am; and then that’s it straight through for the day,
Like if I was to compared I’d say the only things different is that he has more teeth but isn’t walking yet but sooo many babies don’t walk yet, my friends baby was 2.5 years old before he walked, I also see some babies his age can count to ten - there is no point comparing he will get there, I always think to myself when do you see adults who never learnt to talk or walk?! He will get there in his own time, the nap is frustrating, maybe he just wants his nap at a different time and by the time nursery is finished you’ve missed the window.
My nephew didn’t walk until 22 months and was an absolute genius ! Don’t worry at all
Babies all grow and develope differently but talk to your health visitor or gp to get a better opinion than mine lol xx
