All advice gratefully accepted!
My 7 month old had been a relatively good sleeper until a few weeks ago. From about 2 months she's been put to sleep awake for day sleeps and in the evening she has bath-feed-bed routine and usually settles between 7-7.30, usually falling asleep while beng fed and is t/f to bed. She usually woke 1-2 x a night for a bf, sleeps thru the feed and transfers back to bed (usually up to an hr after the feed as I would fall asleep feeding on the couch.
Basically Just after Xmas she started having crappy day sleeps and wouldn't settle in her cot - I'm happy for her to have a little wind down grizzle but I don't do CIO or CC if they are screaming, so I suspected she might be teething and so comforted her and cuddled her to sleep IF I couldn't get her to self settle. I also increased her solids to 2-3 x a day in case she was hungry. Anyway, within a few days she was back to settling well during the day but our evenings and nights turned to custard. She started waking 1/2 hr after going to bed at night and then was up for another 2 hrs before I could settle her, and started wanting a feed at 10.30-11.30pm and at least 2-3 , sometimes 4 times a night, and often wouldn't settle back into her cot after 5am so I would bring her back into bed to sleep with us.
Fast forward 2 weeks and now I have a little girl who is very difficult to settle in the evenings, usually wakes 2 minutes after being t/f into cot IF she happens to fall asleep bf, and otherwise needs me there in her room, stroking her forehead. If I'm really lucky she will sleep in her cot all evening but require me to re settle her every half hour... But more often or not she ends up sleeping, or not sleeping

in my arms most of the evening. Daddy's arms are not a acceptable substitute. And if i leave her she screams the house down until i am holding her again. I even had to ride in the back of the car to sit with her on a 2 hour car trip home on Saturday night as she kept screaming despite my mum soothing her.
By 10-10.30 I usually have had enough and retreat to bed with my little darling who has taken a liking to co-sleeping with her mummy all night long. Attempts at transferring her back to her own cot usually fail immediately, or within 30 minutes. I can now sleep relatively well with her, sometimes having 4-5 hrs of deep sleep at a time, and managing 6-7 hrs in total, which I need to keep me sane and able to work. . and I am quite happy she is safe in bed with us - my arm is around her in a way that makes it impossible to roll on her.
I know heaps of people opt to co-sleep for many reasons, and I don't mind doing it short term for a good reason, as I have done with the boys, but DH is finding it hard to get good sleep, and he finds it hard to sleep on the couch - so its not really I want to be doing for the next few years.
I should mention that in this time she has learnt how to roll front to back, has started commando crawling (preceeded by 2 long nights of very disturbed sleep) and has sprouted 2 teeth as of this morning. And I increased my hours from 3 to 4 short days at work.
From what I have read seperation anxiety can start as early as 6mths and is often starts when babies become more mobile, ie.crawling. She definitely seems to have 'stormy' weeks associated with her developmental milestones as well. For us it seems it's the seperation anxiety isn't a problem during the day when DH cares for, her, but just the evening night. And I can understand that, given I am at work during the day, that she wants to make up for that missed time.
I want to be responsive to her needs and I think i am doing that, but it's hard not to think that I'm creating some difficult habits to break down the track. Especially when most family/friends/workmates who give advice have more mainstream thinking - as I did with DS1 who was a dream baby. And I guess I am finding it frustrating a bit, not really getting any downtime in the evening, especially if I have been working - I really need to fit in some exercise or knitting for weight loss and stress relief.
So, can anyone give me some reassurance? Ie. Age & stage etc/Been there & done that and it got better/life returned to normal.
Please tell me things returned to normal!!! Anything else I can do ???
if you've read ALL that, thank you!!
