宝宝快8个月了，但是我和老公目前都无法把宝宝留在身边，所以只能让宝宝的爷爷和奶奶带回国一段时间。
现在我想问问由爷爷奶奶带回国，都需要些什么手续？？怎样证明爷爷奶奶和宝宝之前的亲属关系呢？？
先说明，我宝宝已经是英籍了。
还有，如果想给宝宝在国内办理寄养签证的话，都需要什么手续呢？？
我在这边网上实在找不到太多的信息，希望有经验和了解的朋友们能助助我
谢谢了~~
My experience of " 爷爷奶奶带宝宝回英国入关" i’m not sure if it will be the same to bring baby back to China.
Sample of:

I (parent’s name), authorize my child/children, (child/children’s name) to travel to (destination) on (date of travel) aboard Airline/Flight # (flight information) with (accompanying adults), returning on (date of return).

亲，你太伟大了~~谢谢你。
请问还需要带什么手续吗？？像宝宝的出生证，或是爷爷跟爸爸之间的亲戚关系证明吗？？？
还有请问你知道怎么公证宝宝的出生证吗？？？
