help !

Rochester

I'm literally having such horrible flashbacks writing this . I had my first 8 months ago via emergency c section. this was after 31 hours of labour & her heartbeat kept dropping . Worst experience ever!!! My recovery was terrible . I had little help from her father because he had to work so much & I just felt so helpless to myself & my new baby . I suffered ppd for a while , I'm just getting over it & some days are still hard . Alot of the ppd came from my baby having weight gain issues, she isn't premature & doctors see nothing wrong but at 8 months she's weighing about 16 lbs . She looks so tiny compare to others her age ! Did i do something wrong?myself & her dad arent big but it just worries me . her development is perfect though .found out I'm expecting baby #2 In June 2018 , by then my daughter will be 16 months. Any one had a similar situation ? Is it too soon ? Will I have another c section? I literally feel myself going back into ppd because I just don't think I can do it . I love my daughter so much & wanna be the best mom to her & her future bro/sis but I just feel like I'm not capable!
