i used to let my girl sleep in her own cot beside my bed till she was about 10mths old iirc. she still sleeps in her cot but then we removed one side of her cot and join to our bed like this Our Precious Princess!: Koala Bear the reason n conclusion.. is all in her blog. hehe. lazy to type all over again. LOL
BUT if your baby is still young like you said, i would sugest letting her sleep in her cot alone to train her to sleep better. btw, are you breastfeeding? the reason why i dont support co sleeping at such young age is because IF you are breastfeeding, most of the time you will just shove your breast to the baby while you n baby are still lying down n baby will most likely suck her way to sleep which is not very good for such young babies as they cant learn how to fall asleep by themselves n might grow dependent on the breast.. my girl is already old enough n knows how to go to sleep by herself so i dont mind co sleeping...now she just come to me, suck n crawl back to her own cot n fell asleep. sometimes she does fall asleep on my breast though but not often.
