sleep schedule

hi mummies. my baby is only 1month old plus. i realised my hubs have bad habits with sleep schedule that causes our girl to cry alot at random timing. so recently while he was away for few nights for work, did a sleep schedule test for my girl. she feeds every 2-3hrs so i tried to fit in with the schedule. it WORKED as my girl is able to sleep thruout the night with little to zero cries (unless she poopoo?) sooooo i told my hubs abt it and he said that our girl is too young for any sleep schedule. i was like hmm true but need to start somewhere so that she and us can have a rest mah. he said dont need.i was like ok lor up to you. isit wrong for me to put the sleep schedule (not strict/flexible) in place? ? i felt that my girl milestones are quite fast as observed so putting schedule in will be good. i also realised that i managed to get 1.5-2.5hr nap uninterrupted hahaha
