Can I maintain weight the rest of my pregnancy?

Micky • 💙 Boy #2 Due October '21!

So I'm due April 6 with a baby boy ( yay!!) But I have already gained about 26 pounds with 8 weeks still to go. I'm a small girl (5'2") and I worry about my baby growing too big to come out (I want a natural birth), or having too much weight to lose postpartum. My husband was 12 pounds at birth and my last ultrasound my baby was measuring in the 96th percentile for size. I eat pretty well, but a fairly high fat, high protein diet (from good sources). Do y'all think its okay to maintain weight during pregnancy, or at least gain no more than 1/2 lb a week (4 more pounds total). Thoughts/advice/opinions? (I will be asking my doctor as well)
