She is only 6 days old - she has gone from being at the perfect temperature, constantly held and rocked, never hungry or thirsty, constant gentle rhythmic shushing noises to bright, too cold/too hot, loud harsh noises, hunger & thirst, being apart from mum, all these new skills to learn.
Is it any wonder she wants to be held and to suckle?
I don't mean this in a sarcastic or bitchy way but in the sleep deprived haze of the first few weeks of a baby's life it's easy to forget they haven't read what they are 'supposed' to do and don't go to sleep in the cot if they are put don sleepy but not yet asleep, go 2-3 hours between feeds, gain 6-8 oz a week (after regaining birth weight that is!), sleep in 6 hour stretches......
At this age feeding constantly, wanting to be held constantly, not liking to be put down or left is completely age appropriate behaviour.
I also felt proud that I was my babies comforter, it showed they were bonded to me. Fecking annoying though when you need a wee but you gotta take the rough with the smooth
Good luck with the mw.
