you can try staying in bed with her till she starts to wake up and as she is becoming active but still asleep, pat her down. it may or may not work. over a few nights, she will probably stop waking up. I would try patting back to a deeper sleep and with the next waking, feed her then try to pat back on the third waking. If at anypoint they seem to be waking up more than falling back, just feed back to sleep.
i agree that this time in a baby's life is so short and fleeting. It won't be long she will want to be in her own room. Promise. Enjoy the time you can.
Re: grown up time. Parents make all sorts of similar sacrifices in order to look after their children in the early days. Later on, when the children are older, difficult times like these are what hold couples together. For example, some couples, work shift patterns so that one partner is at home to do childcare while the other is at work and then swap shifts. This type of accomodation may come out of necessity but in the big picture, we make choices like these.
In our culture, there is a big emphasis on time away from the kids, which always seems a theme of guru books. When we shut the doors on our kids at a young age, we teach them to shut the door on us when they are able to do that.
My dd is nearly 3. We coslept so that everyone can get the most sleep, not because we believed in a philosophy. I am also lucky enough to be brought up in a culture where parents routinely roomshare or bedshare so it was easier for me to turn to dh and say, ffs, she will sleep with us because I can't get her to sleep alone. From around 2.5 yo she had her nights when she wanted to sleep in her bed, in her room eventhough we have never, not even gently, persuaded her to start. Now she wants to sleep in her room every night and sleeps there from 8-9pm till 5-6 am. There have been no tears from any of us to reach this stage. For some kids it happens sooner.
When there is no push to get into their own space, they make the move when they are developmentally ready to do it. Our job is to listen to their cues respond to them.
The link is from a very wise woman which i reread the other day. It doesn't apply to your case directly but I think you can put the framework of where you are into this picture.
as a final thought. my dd who is allergic to cow's milk and egg took longer to wean onto solids as most children do. it means she fed a lot more at night for a longer period of time. I am now pg with my second and once I got to 5 wks, i realised taht her feeding 2x between midnight and 6 am was too tiring for me. (this is only a couple months ago and she will be 3 in a couple weeks) I expected a lot of tears weaning her off those 2 feeds but i was pleasantly surprised that she only mumbled, rolled over and went back to sleep. By the following week, she was 'sleeping through' and demanding to be in her own bed. I suppose I could have gently persuaded her earlier but to be honest, dh and I have grown to love her company in bed for so long, we didn't consider it and last night for the first time in two weeks, she slept in with us because I was too tired with pg and the flu to go to her room with her. everyone slept like throught.
