Worried about milestones

So I know it's probably ridiculous but I'm worried about milestones with my son who is 2 months old... I keep worrying about walking and talking and all that. mostly because we have family members who compare their girls to him. it's making me anxious that I'm not doing enough for him or doing what I need to be as a first time mom. I don't have much of a support system mostly just ppl trying to one up and with my lo I am trying to have a backbone but in the back of my mind I'm still worried
