Mine are 15 and 9 now - so bear with me! :)
When ds1 was born, it was a long difficult labour, and he had to go to SCBU for a while.
I was still puking as they hauled me into my postnatal bed. I hadn't slept for 3 nights, and when they wheeled this baby in after me in, in his 'goldfish tank' I burst into tears. When asked what was wrong, I said " I've been in labour for 3 days, I've been cut from arsehole to breakfast, I'm still being sick, I feel like I've been runover - and now I've got a baby to look after?" (I was beside myself by this point, and hadn't had chance to bond)
the midwife was lovely, and very canny, and said "Aaah - i'll give you an injection for the sickness - why don't we put him in bed with you to warm him up - we'll keep an eye on you, and if he stirs, just press the buzzer. I grudgingly agreed, and we snuggled down - me with a suspicious eye out for trouble!
I stared at him, wondered about him, felt nervous, put him to the breast - he latched on, after a while, he came off, looked at me -and suddenly - it was like waking up to the best ever Christmas morning ever! WOW! This is MY son!! He's really really mine! And I haven't seen him yet properly - I carefully unwrapped my son, to inspect him and all his bits and pieces - his willy, his tiny toes, the tiny down-like hairs on his ears, the stork mark on his neck (he looked like a bat!), then hurriedly wrapped him up again - and beamed - and beamed again! Then the midwife came in.. "Had enough yet? shall we put him in his cot?" she said casually.. I clutched him to my very ample bosom as if she was off her rocker " No -erm - I think we are fine - thanks though..." Stitches? what stitches?...
But I never could really co-sleep, although I wanted to. I'm very much a 'sprawler' and could not sleep myself, having a tiny baby in bed with me - I just couldn't relax - that was just me though...
They slept in a cot right along side the bed, so I was there for feeding, and touching etc, but I couldn't sleep with them actually in my bed.
Interestingly, as they got older, they moved in and out of my bed quite a lot- but not when they were tiny - it was just that I couldn't sleep when they were so vulnerable, but that was just me. I'm not au fait with the current advice, as I'm struggling with different issues (GCSES and such-like) so can't help you there.
Not much help really - but hey! looking back at how it all felt - the whole bonding thing etc makes me quite envious! Good luck in 3 weeks time! x
