I've fallen into a habit of letting Tamsin sleep on my lap (or DH's lap) until I go to bed (we're co-sleeping). I enjoy it, but it would be nice to have some time alone with DH in the evenings too. I've tried putting her in bed (either ours or her cot) but she wakes every 20 minutes or so and takes 10 minutes or more of cuddles / BF each time to go back to sleep, which gets frustrating, so most of the time I just don't bother trying to get her to sleep alone. Should I try harder to get her used to sleeping alone for those 2-3 hours between her usual bedtime and mine? What sorts of things might help?
