Help a single mother to reunite with her family in South Africa/provide humanitarian aid

When COVID first hit, my son got stranded in South Africa and was unable to return with his new bride. Years have passed and one thing after another kept coming up , two precious babies were born, and they were never able to afford to return to the USA. I also have limited funds and have never been able to meet my grand children in person. I’ve always felt called to Africa to help communities build self sufficient homesteads/farms. It turns out my dreams have rubbed off on my son! He’s currently working on trying to build a self sufficient farm that will eventually turn into a place to receive orphans and trafficked children. Now, they are expecting their third child and the doctors are very concerned. They have advised my son and his wife this is the last child they should be able to have and it will need to come via cesarean section. I have been watching flights for some time and recently have noticed they have come down some. Also, for the first time, I have people able to watch my little farm and also have transportation to and from airports on both sides of the trip. I have listed many things for sale to cover the cost but have not made enough to cover the full cost currently! ($4000-6000 for my 2 younger children and myself) It would mean the world to me to be able to go and be there for my grand daughter birth, meet my grand children, be able to assist after surgery, help build the self sufficient farm , and start getting food out to the surrounding communities that suffer from great poverty. I’m running out of time to get a decent flight before the babies birth and so, I’m reaching out to see if anyone might feel led to bless us financially or prayerfully for this journey. Thank you for your consideration and prayers!

P.s. if for some miraculous reason, more funds come in than is required for travel expenses, I will be using it for the humanitarian aid part of the journey!
