Calf exercises !!?

I've had little calfs for as long as I can remember- it's something i've always been self conscious about.. I used to be 95-100lbs so I could get away with it because everything else on me was tiny aswell.. But since having 2 kids and gaining some weight (about 15lbs, which im thankful for) it's gone everywhere else other than my chicken legs. I've googled a ton but I feel like getting personal opinions will help. I have started going to the gym about 2x/wk so anything that can be done there or at home even would be suuuper appreciated. I've avoided wearing dresses/skirts all my life because I hate showing my legs.. I just want to be proportionate😕 Thanks! Any tips/tricks/experiences are welcome :))
