Language explosion at 22m!

My son has always been at the end of the curve for every milestone - rolling at 7 months, walking at 15.5 months, etc. I was getting worried about his language development around 18 months - he had maybe 8 words total - but has been steadily progressing so it's not quite been at intervention level, but I've been keeping that in the back of my mind as possible/probable. Then, all of a sudden a couple of weeks ago, the language explosion happened and it's like a miracle! He is repeating everything, trying to sing his favourite songs (Wheels on the Bus, Itsy Bitsy Spider, Twinkle Twinkle) and most critically, picking up and putting together all sorts of 2-word phrases. Wanted to share as a hopeful story for any parents who might be where I was a couple of months ago! Would love to hear other stories of the language explosion around this age, it truly is so fun and feels like a miracle 🥰
