Baby is still young - assuming you mean 1 month - and loves to be near you (warmth, familiar smell, heartbeat, movement etc is all so familiar to when they were in the womb). Just so what works for your family. Sleep isn’t linear...it changes all the time. I feed to sleep/nap or carry to sleep as it works for us, also baby falls asleep so quickly, no need to sleep train as long as you can manage!
