baby weight

At 36 weeks I had an ultrasound and baby was weighing in at 7lb 8oz. We are getting induced at 39w 1d and I’m really nervous he’s going to be a 9 or 10lb baby. Plus daddy has a big head and I’m worried he will have the same. Lol I have always handled labor well, but now I’m scared. My girls were only 6 and 7lbs. I know everyone is different, but has anyone delivered a baby that big? Any words of advice to make it easier on myself? I will be going natural. I didn’t take anything with my girls and do not plan to this time either. My niece was allergic to what my sister took and she almost died. So that is a fear of mine.
