user1466685631 good luck.
Please just go easy how you introduce people, I know baby is young and there is a temptation to think that they will not know what is going on ... but... if people want to hold baby, as they will, you may find baby quite confused. They will be seeing sights and smelling smells and hearing voices, their hearing is highly developed, the best ever from birh (unlike sight). They won't have the language to ask you 'Who was that?' or 'What relation to me are they?'
Our son was 3 (almost 4) when he came to us. I think we waited over a month to introduce him to my parents-in-law and about a further two weeks to introduce him to my sister, and a further two weeks to introduce him to wider family.
Friends took even longer although we did prioritize local friends who we see a lot and as we have dd, birth child, who was 9 at the time she was seeing friends and I was walking her to school so local friends just met him as part of life.
Remember your aim is not to avoid contact with the wider world or to avoid contact with relatives it is to build attachment and an initial bond with the child. TOO MUCH or TOO EARLY contact with friends and family may get in the way of that, so take advice and go slowly, because when friends come round your attention may be off baby and baby's attention may be off you, that (IMHO) is the issue. It's not necessary to be quite so strict with birth children because they have been listening to your voice from about 23 weeks in vitro, but even mums to birth kids may want to limit how much they see people and just spend time with baby.
Exciting times. It sounds great.
Good luck.
