I tend to agree - really watch your child and maybe be a bit overprotective at this stage of transition. Dont let others hold the baby if he/she acts the least little bit upset. Keep contact with people that wont be regulars in the childs life to a minimum. I wish I would have just been rude and told folks to not visit, have parties, etc. We had two showers and several uninvited visitors after we brought the kids home (within the first 2 weeks) on every occasion our toddler (then 17M) would get very stressed. We opted just to get some of these social obligations out of the way early, but it was difficult. He would bang his head on the floor, furniture as a reaction to stress and we always had set backs with this when his routine changed, or new people came around. He stopped bangin his head after about 3 months home - now he's just a regular throw yourself on the floor and kick and scream tantrum type on those rare occasions when things get to be too much
. But then it was very obvious when he was frightened or overstimulated. Even now a year later, when my dad and his wife come to stay with us, both kids get wild by the end of their trip due to the change in routine and everyday schedules.
The early childhood intervention specialist told us that for every day of change or stress you'll have at least two days of behavioral set backs. I'm sure that isnt a scientific statement, but boy I've found it to be true with ours. Play it by ear tho. Our baby girl (9m when first at home) loved attention. Each new person was another she could get to hold her while she jumped and moved her legs. She was not at all troubled by new people - some sounds frightened her. But we would have had no problems with her at that point. Our issues with her were trying to make her a little more dependent on us rather that making her feel secure so she would be less so (like with our son). Each child is different.
Good luck,
