The baby in cot in own room is fine and grand and no problem.... If if the child is sleeping.
Realistically, if you are back at work you are not going to manage nights where you are up and down and up and down all night. So I would put good money on baby ending up cosleeping. You'll be too knackered otherwise. And if you end up cosleeping, I can imagine you'll look back and think to yourself why did I battle against it so long?
If baby is in own room and sleeping, tger e is no issue
If baby in a cot in your room is better for you than baby in your bed, do that. You'll get no less sleep, just much, much MUCH easier dummy reinserts and resettles.
Baby will eventually learn to sleep through. I can't understand the rationale of people wanting to keep walking back and forth to a baby waking frequently in another room.
I just thought of another idea - a bed for you/DH in baby's room. If baby in own room is that important to you, that would be another way to get some sleep. It's another rationale I cant understand (wouldn't your own bed be more comfortable and convenient?), but lots of people do it.
"I have created a needy baby"
Yes, you have. You and DH conceived that baby.
In my experience some babies are needier than others. I've had 2 needy children, two not needy. But my attitude to my two needy children was markedly different (see above post)
I fought against my eldest needing me so much. I denied her my comfort. I felt stifled by her needs. I insisted she slept independantly early on. Because the teacher/disciplinarian/control freak in me said that was "right".
I learnt by the time DC4 came along (after two hands-off laid back babies) that fighting against it only made matters worse and harder for everyone. So there was no point or benefit. Just a complete waste of energy all-round.
I'm sure you can guess which of my two "needy children" sleeps the best. DC1 didn't sleep through until 2.6y, continued to wake regularly for reassurance for years and years. She'll be 13 soon. Still sleeps with the light on. Still comes to sleep in our bed on occassion (the boys never, ever do) in the middle of the night. DC4 has really healthy and secure sleep hygiene. Because I embraced her neediness and took things at her pace every step of the way. Evidentally she just needed 12 months. 1 year really isn't that long in the grand scheme of things.
