So I just had my baby 5 days ago. My mom has been helping out. Today she asked me why I still had all the clothes pre pregnancy if they weren't going to fit anymore. Like I just had a baby I don't want to think about my weight right now. I was very tiny before a size 1 and weighted about 115 I gained about 65 lbs during pregnancy.  But it's not just her my mother in law has told me that I won't be tiny anymore. My SO has said the same thing. I just feel like everyone expects me to be fat now. This is just bringing me down I plan on working out when the doctor gives the ok. I just wanna know am I being unrealistic? Should I not expect to get my pre pregnancy body back?
