I need some help ladies

I have a 9 month old baby who sleeps eats and plays when she wants to I don't force her to do anything at certain times I feel like she's her own person she will when she's ready or I'll start trying when she's at a certain age anyway bd says I need to get her to be on a schedule I guess cause he wants things his way. Do y'all think it's to early or just in time for a schedule he only has her every other weekend BTW. Am I wrong? Thanks.
