Dd 2 1/2 has, up until about 2 months ago, always slept alone in her cot. Then she had a really nasty cough which went on and on and also potty training and starting 2 mornings a week with a childminder. So I got in the habit of sleeping with her on a mattress in her room. Previously she wasn't a child we could co-sleep with even if we'd wanted to because she didn't seem to like it (likes her own space). Now what happens is that for naps she sleeps alone in her cot very well and goes off at bedtime alone well too. But about 3am she calls for me to sleep with her and I haven't resisted. The reasons are that I actually quite treasure sleeping with her because I've never been able to do it before and because I am an extremely fond and protective kind of mum who sleeps with the baby monitor pressed to my ear virtually when she's on her own in her room (she's 2 floors away from where we sleep so we can't do without a monitor) so being right next to her I sleep better, she sleeps better and longer in the morning than she's done in AGES.
BUT am I making some kind of rod for my back that I'll regret at some point in the future? I always thought that co-sleeping was other people's pleasure / problem, it's all new to me.
