13 month old sleep

[gem149]

My wee boy is 13 months old and for the last few months has been waking up through the night 3 or more times. We have a co sleeper cot which he usually sleeps in, he feeds to sleep and the only thing that will settle him back to sleep is feeding him. He also has a pacifier. Now that I'm back at work I'm finding the multiple wake ups difficult. Wondering if he would wake up less if he wasn't beside me? Or if I got him to sleep at night with his dummy rather than feeding him would he be more likely to go back to sleep through the night with his dummy? Does anyone have any similar experiences?? Have thought about having him sleep in a bed with daddy instead but concerned he'd just get upset if I wasn't there through the night. Thanks in advance.
