There's certainly nothing wrong with mum's having 'me-time', if that's what they want. I wouldn't - I know I wouldn't enjoy myself as I already leave Anna for two hours a week for my driving lessons and it makes me really uncomfortable, I'm constantly worried about if she is crying, or needs me, or I just plain miss her: I love spending time with her, and when we aren't spending time with together I miss it.
I will leave her when I am ready, but I'm not yet, and there's nothing wrong with that. When she's one we plan on putting her into nursery for one day a week, and when I do my degree in 2 years or so she will be in nursery 3-4 days a week. We won't be attached forever! It is such a short space of time where they are dependent on you like they are at this stage, so I want to cherish it and enjoy it. I don't want to rush into her not needing me.
I would say that breastfeeding does make me feel very attached to her; nobody else can feed her! Nobody else can make any problem go away, instantly by just whipping out their boob for her! Nobody can wake her up from a nightmare and calm her instantly.
I feel the need to point out that I am not making ANY sort of dig on bottle feeding mothers or the way they calm / soothe / feed their baby - just that MY baby has been breastfed and therefore what she knows as her comfort is my breast. She won't take a dummy because she doesn't know how (different sucking action to the way they suck / lap on the breast).
I do feel that nobody else can look after my baby for a substantial period of time yet, especially not a whole night. I also wouldn't trust any of my family not to feed her meat and to respect that until she can make a choice / ask for meat then she will be given a vegetarian diet only.
She's my baby and she won't be my baby forever. I hope people can understand that it's not just that I don't feel I can leave her, but I don't want to.
As for having people who are willing to look after my baby and being grateful for that, I am very grateful for the support that we have, however I would appreciate them accepting my decision that I don't want to leave her, and for them to stop pestering me about it and telling me that I NEED a night off. I don't need a night off, and I don't want one, either.
