I am co-sleeping with DD2, 4 months old. Which is fine and works out really well during the night as when she wakes I hardly notice, she just latches on and then I go back to sleep. But the problem is, she is generally ready for bed at around 8-9pm. So I take her upstairs and lie with her feeding her until she is well asleep, then go back downstairs.
10 mins later she starts grizzling. So I go and lie with her and feed her again until she is settled. Repeat every 10 mins until either I give up and go to bed myself or she comes back downstairs and grizzles there as she is actually dog tired.
She will only stay settled in bed if I am next to her but I don't always want to go to bed at 8pm! I resent not having at least a bit of an evening to myself.
