Moms opinions

So I gained a lot of weight after having my first born. I went from working an active job 45-50hrs /week to staying home full time and I had gestational diabetes while I was pregnant so I binged chocolate and everything else not good for you after I gave birth. I don’t wanna specifically say how much I’ve gained but definitely an unhealthy amount of weight. My question is, now we’re thinking about trying for baby #2, do I wait for baby number 2 until I’ve lost some weight or do I try to lose all the weight after we’re done having kids? (We’re planning on 4- roughly 2 years apart) any advice or helpful input would be great, please don’t be mean, I know I shouldn’t have gained the weight and could’ve done things to avoid it, but we’re here now and I would like advice or input from women that have been in my shoes. Thank you!
