Also to the PP who said co-sleeping makes babies too attached. I don't understand how it is even possible for an infant to be "too attached". For us co-sleeping has been amazing and especially in the early days is the only reason we get any sleep!
This is just my opinion, just by what i have seen and been told, like i say, a friend of mine has her baby sleep in her bed with her, she says she regrets this as now her 1 YO baby wont sleep anywhere else but in her bed or next to her, she cant have anyone else look after her LO over night, she recently had a party to go to she couldn't drink all night and had to disturb her baby sitter to pick LO up late at night so she could take her home to bed as she wouldn't settle sleeping else where.
I know your baby is far more important than a party and im not saying i dont want to co-sleep just so i can go partying, that's the last thing ill be doing, but for any reason when a overnight baby sitter is needed its not fair on both baby and baby sitter!
i also see the dangers in co-sleeping, and by co-sleeping i mean sharing a bed with you, not the cribs that attatch to the bed. ive heard many stories where parents have laid on their baby,
my OH's gran knows someone who put baby in bed with her, she is a light sleeper and usually wakes to anything, on this particular night she woke with the baby laid at the bottom of the bed and the baby had suffocated through the night. id be far too terrified this would happen so personally wouldn't take the risk.
Im not judging any parent that bed shares, its entirely up to the individual, i think its great many people manage it and have the best of luck with it, i just personally would rather have my own space and give baby his own space too.
