He’s so fast crawling
That's great! It means he's got all of the strength necessary to walk (when he gets around to it). It'll be okay 🙂
It feels like he’s scared to walk independently
Mine was similar and didn’t walk until he just turned 18 months, now (21m) is a great walker, can run etc. it was a bit worrying but we just kept gently encouraging it but trying not to put too much pressure.
If he's cruising, crawling, climbing etc then it's fine. Mine did all of this for months but then didn't actually start walking until 18 months. Then when he was off you couldn't stop him as he'd built up so much strength doing all of the other pre-walking skills. Just keep encouraging him and he'll get there in his own time.
