Its hard hun, Big hugs!
Neither of my boys were feed/play/sleepers and DS1 would go into hysterics when ever I put him down as a baby, so I borrowed a front pack and put him into that. It let him be close to me and sleep when he wanted (it also helped with his cronic reflux)
My sugestion is to not worry too much about what you are "suppose"to do, do what you think your baby needs. Watch baby, really work out her signalls tired, hungry, lonely and when you have those down pat you will feel more confident that your giving her what she needs and perhaps work out whats going on. Does she have colic? silent reflux? or just going through a unsettled time, most babys have those times. Your doing great hun! Really
