Glad you're not near the earthquake spud. So scary.
Embeth my mum said my sister (she's 19 months younger than me) didn't crawl, walk, talk until quite late and she thinks it was because I was always helping her so she didn't feel she needed to! Maybe being the youngest of 4 she's entertained with the others and is happy watching them like my sister was? Sounds like her fine motor skills are excellent too! She's also only 9 months! Annabel only started to properly crawl at 9 months. Try not to worry, she's just got you worked out and knows she doesn't have to move yet 😂👍🏻
