Weight loss and fertility

Backstory:

I am about one year postpartum. I had a c section. My maternal fetal specialist recommended that I wait until 24 months to start trying again for another baby (baby number 3). She explained that in my situation it would give my body the most time to heal properly.

I am having a hard time waiting because my baby is giving me baby fever.

Also, my main question is about weight loss and fertility. Right now I am 200lbs-205lbs. I want to kick it into gear this new years and healthily lose weight. Will this make it easier to conceive at the 24 months? How do I take my mind off of wanting another one so soon? Did anyone else get pregnant with a 2 year old? How was it? How close are the kids?

Thanks in advance!!
