Second time mom in 11 year apart difference

Are any other moms staring over completely? My first is 11 and I’m 7 weeks today. I’ve been trying for 7 years. I’ve always wanted at least one more but I’m not going to lie I’m scared of the what if’s and all the differences from when I was in my 20’s. Any advice on what I need? Or things that are newer that I need to look into?

Update:

Had my ultrasound today and my 11 year old was there and she’s so excited.
