Hi
Your little one is still so young and like all babies just wants to be near mum all the time. It is great that she sleeps well all night. From personal experience i fed to sleep if need be for the first 2-3 months and rocked to sleep, but that was my personal preference. If you are keen to get your little one sleeping in the cot, i would try doing that just for one nap a day, so for your first nap try getting her to sleep using shush pat, so she gets used to the feeling of falling asleep in the cot. Otherwise swing, sling and the rest that gets your little one rested are good.
