Dont feel 'THAT WAY ' about my woman since SHE HAD A BABY?

Can u ladies tell me how long will it be before my woman trims down after having our first kid? Shes a looker but at 8 months gone, as you can imagine, shes put it on places a woman should be fitter. Also the bedroom has taken a real nose dive these days and i'm struggling with mens needs. This has led me to the arms of a few new woman of late, but it means nothing to me, its just release. I have to admit, with her being poled, i will not see her in the way i need to see her to fulfill my needs. I will see her as mother of my baby now...end of. So i hope we can have a few more kids but i dont think our bedroom relations will be as satisfying for me. I know some of my mates, their woman have kept themselves from sliding but then other woman are letting it slide so i just hope my woman doesnt turn out in this bracket. I'm a mans man, so any advice? By the way shes working full time as i cannot find work right now and when this nippers 3 weeks, my mother n sister is going to help me rear it so my woman can keep the dimes rolling in. Her mothers startin to whing about it but i'm a man and i need a job that will make me feel good about myself, not one that just 'helps put food on talbe'
