May I suggest co sleeping? It's beautiful and gives your child so much security. It's completely safe unless you're a drinker or a druggie..... It doesn't sound like you are. I think it's great you're continuing to nurse. This is such a special time in your life and it goes away so quickly.
If you co sleep, you will sleep really well, won't have to get out of bed and take her up and risk her waking as you put her back into her bed. She will naturally snuggle up to you, feel your warmth, comforted and sleep well. You say she's waking to comfort, it's a win win situation.
Co sleeping children grow up to be very independent, secure and loving people. Not saying non co sleepers don't but some worry that is they co sleep children won't become independent.... Not true.
Good luck!
