Some times I accidently miss my babies cue to have first morning nap about 9am, when i do he becomes over tired and he really fusses about going to sleep and then will sleep fretfully waking after 10 mins and then 30mins and will then wake cranky and not feed properly and then activity is useless as over tired, but won't go to sleep again, and then the day is ruined as he continues to not sleep and therefore feed properly so he spends day grumpy with hunger and tiredness. When I catch him in time he's an angel baby and sleeps 3x for 1.5 hours and goes down at 7pm no probs. Is there any trick to save the rest of the day if this happens? How do I get him to take the nap? Ben is 7 weeks old.
