I'm very fortunate that my 4 week old daughter has become quite a good sleeper already. She will have 3-4 hour sleeps during the day and sometimes will sleep 5 hours during the night. I have been told that babies shouldn't be awake any longer than 1 hour, however sometimes she is awake, alert and happy and really isn't ready for a sleep for up to 1 hour 45 mins(on the rare occasion). I put her in her cot anyway and sometimes she's happy others she is not. Would it be so wrong if I kept her with me until she was tired and then I put her down?
