Breastfeeding and weight loss tips?

Hi! It’s been 3 months since I gave birth to my little boy through cesarean section. My pregnancy was quite stressful and I must admit I found solace in food (wish I hadn’t). Now, I’m exclusively breastfeeding my baby and I have 45 pounds to lose but I’m scared my calorie deficit diets may affect him. Anyone here who lost weight while breastfeeding?
