At what age should you start a strict bedtime routine? My DD is 4 months and she doesnt really have a routine yet. We or i (depending if DP home from work) bath & feed her early evening and then she comes back downstairs with us until we go to bed. At what point should you introduce a 'bedtime'? I was told by my HV this doesnt really need to happen until 6 months ish. Is this true? Ta x
