When my little ones where baby’s we never really struggled they went in the own cot and went to sleep on there own and night feeds we would hold as little as possible, it was difficult if they had a bad night but power through and they will get there mine now sleep on there own and go to bed on there own supervised. We had a heart beat bear that they slept with as baby’s after a few months we took it away as didn’t get used but would defiantly recommend a heartbeat bear when first born as it comforts, from what they were used to in the womb.
