When did your baby start to sit on his/her own

So by how many months did your LO start sitting on his own without support?

When did you first start holding him/her to sit with support ?

My son is 5 months old and still wobbles to sit. He will sit on his own without support for 5-10 seconds and then falls over lol. Just wondering when he’ll start sitting on his own... I’ve seen other babies sitting on their own by 6 months
