Nope! My baby was the same. She also skipping crawling and was walking by 10 months.
Perhaps take her to a chiropractor ?
I put my baby in sitting position this morning & she was chilling just sitting by herself. Guess she was ready just didn’t realize it. She’s always wanting to be on the move chasing after her 2 brothers. You should not be worried
My baby is also crawling & climbing on everything. She is still not sitting by herself. I would not be worried @ all
