What's "a little over a week ago"?

[Kootaka]

(1)What's "a little over a week ago"?

--------
Jennifer wanted to show Colin that there were many people who cared for him on his birthday, so she created a Facebook page a little over a week ago, with the intention of showing it to Colin on his birthday, March 9.
--------

I thought that "a little over a week ago" means 6 days. Is it correct?


(2) What's meant by "put a bunch"?

--------
Things like lights and sound and changes will cause him to melt down,' Jennifer told Wood
TV.
'When you put a bunch of 10 year olds and one who acts like that, and they are all going, "What’s wrong with that kid?" You know, it’s hard.'
--------

I don't understand what "put a bunch of" is.
Please explain to me about it.

I'd appreciate your help.
