What is your bedtime routine for 3-5 month old baby?

at 3 months i started introducing my son to cereal. it says for babies who sit up but ur best luck is to pump the last feeding and bottle feed her and mix just a lil cereal in to the bottle n just bairly like bairly slice the nipple just enough so the cereal and milk can get through! SHe should sleep a lil longer it will stick to her tummy n keep her full! My son slept 5 hours a night! now he's on stage 2 foods at 6 months and sleeps 6-9 hours a night!
