Establishing Day and Night 🌞🌚

Hello fellow moms! Kelan and how did you establish day and night routine? My LO is 1mo and 12days, kalat padin sleep sched nya. Sabi naman ni MIL hayaan lang daw matulog nang matulog kasi nagpapalaki, tho ginigising ko sya for feeding every 2-3 hours, pero minsan umaabot ng 4 kasi nga ang himbing ng tulog. Any tips naman dyan? Thanks! :) #SharingisCaringTAP
