Hi Rabbit, I just touched on this on another thread, but let me say in general I think you should decide how much cash you would like to give and then give it at the end of your journey when you say goodbye to your surrogate and her family. My feeling is that they are fairly treated and compensated for what they do from Dr. Nayana and it is really a bonus for you to give them more because you want to and are able to. However, keep in mind they really are extremely poor compared to us to a degree that is hard to even comprehend.
That said, it can just create a very uncomfortable situation if you give gifts or money in the beginning because then it is likely you will be visited by the rest of the surrogates family as they try very nicely to extract more money and gifts from you.
Our own experience was that our surrogate and family came asking us for things even as our baby was in NICU and lucky to be alive and we weren't sure if should would even survive. I finally had to have someone tell them to leave us alone and that we would contact them when we were ready to talk to them and give them anything. We then did give 20,000 Rs before we left.
We also gave 10,000 Rs to Rama hotel staff before we left, but we were there for many months. Their longest staying guests ever we were told
The concept still hold though. Rather then giving small tips to the dozen or so hotel staff you will likely interact with, just let them know that you will take care of them before you go. This has the added benefit of giving them incentive to treat you well until then.
Another thing I think everyone should consider is giving to some local charities. We asked Dr. Anita because we trusted her to find some needy charities and we ended up giving money to a leper colony (did you even know they still existed?) and to another group that helped very poor women and children.
I would say that you should think about how much money you want to give away ahead of time, and think about who and when you want to give it. But, then when you are in Anand focus on the task at hand and your baby(s).
