Idk what to do with my baby as a stay at home mom..

So first off I feel like I’m completely failing at this mom thing. I’m a first timer and I’m completely lost on what I’m suppose to be doing with my baby at 7 almost 8 months.. I try and play with him or whatever else or go for walks sometimes and it’s just starting to feel like I’m not doing enough. I guess more on the talking aspect or learning. I am personally a more on the quiet side person so for me I have really hard time making the effort to talk sometimes because most of the time I internalize a lot of what I am thinking. And I have asked before how much moms have talked to their kids and out of the few responses I got they said they narrated their whole day or talked 90 percent of their day... and idk i have tried harder to make sure I’m more interactive with my baby and idk if it’s because he’s in a sleep regression and I’m exhausted or what but I just feel like I’m not doing enough to meet his verbal needs... my husband says I talk to baby enough when he’s around that even if I’m not overly verbal during the day I’m making up for it at night.. I just don’t want to let my baby down when it comes to helping them along verbally.. but I’m really struggling
