Will I lose my baby fat during puberty?

I'm fourteen and over the last year I gained 35 pounds while I was in baseball and never had fast food hardly ever but I still have boobs (they can dance a little) but they’re still unattractive and none of my veins pop out yet, my brother lost his when he was 15. But at 14 I can't seem to wait any longer I workout regularly and have gotten stronger but I still fat on my chest. Any help here?

Answer:
This happened to me when I was 13. I have always been very active in sports but right around 13 I started gaining quite a bit of weight. By the time I was 15 I had grown about 7 inches and I grew into my new weight. I think your body is just getting ready to grow.
