Am obviously a crap mum for not knowing this, but not sure what co-sleeping is!!!!
Is is sleeping IN your bed, ON your bed, in an attached co-sleeper but in a separate enclosure, or in a basket/crib/cot next to your bed?
Does it only refer to night, or are you co-sleeping if you dc naps on you on the sofa during the day?
Feel amused that I might be doing it without realising!
