I am looking for different experience regarding babies soft spot on their head

So my baby is 2 and her soft spot has not closed yet, I told her pediatrician and they are giving it 6 months before they look further into this because they said it should have been closed already. They took some blood and ran tests but everything is normal, my baby is developing normal aside from this. Shes very smart and healthy. I don't want to worry but this did not happen with my first baby so I'm confused. I will wait to see what her pediatrician suggests but in the mean time just looking for any other moms that may have experienced this or what the normal time frame is for the soft spot to close. It's not causing any pain, nothing abnormal, I'm just a concerned mama.
