Postpartum weightloss

I don’t know that I still technically qualify as “postpartum” but my little girl just turned 7 months old and I have been STRUGGLING to get these last 15 pound off! I gained 30lbs total but was on bed rest/ modified activity most of my pregnancy due to hyperemesis, dehydration and uterine irritability so I know I’ve lost a ton of muscle mass and UGH! My body composition has changed so much and I am carrying so much extra weight in my tummy and love handles and I just want to get it off! I am currently doing a restricted calorie diet and working out 4-5x/week but nothing seems to be changing. Does anyone have any other recommendations that helped them get the last 10-15 pounds of baby weight off??!
