You know how the midwives tell you your baby shouldn't go longer than 3-4 hrs during the day without food and no more than 5 hrs during the night... how long should you be following that guidance? DS is 3 wks on Monday and wants feeding every 3 hrs fairly consistently anyway but I was reading up on dream feeding and wondered when we could think about starting... (I know not yet, but I'm a lady who likes to plan ahead!)
