XP- Losing Weight after Pregnancy

This is a cross post but, I was curious if anyone has had any experience with losing weight after having a baby after WLS?

How long did it take you to lose your baby weight??

I am 3 years post of RNY as of this year, I weighed in at 132 pounds in Sept 2011 when I found out I was pregnant. I gained 23 pound with my pregnancy, weighing 155 pounds when Baby Girl was born, it is now 4 months post pregnancy and I have only lost 12 pounds weighing in as of this morning at 143.  I have about 13 pounds to go to where I was at before the pregnancy. 

How long did it take you to get back down to your pre baby weight and did you go straight back to WLS basics?? 
My dietician is of NO help and I seem to be getting nowhere with my weight loss. 

 My youngest will be six on Saturday.

I, uh... well...

Well I.. Uh.. Still think you are Wonderful 

 Heh.  

Well, she was worth it.

Thanks, I truly believe my lil' one was worth it too.. It is one of the reasons for having had WLS.

I just need to remember that even though I have "some" baby weight to lose, I am still down 100 + pounds AND have had a Baby. 

Thanks for your replies
