DD is 5 weeks old. HV said this morning that I should just let her sleep as long as she wants to (although no longer than 6 or 7 hours especially if it's during the day!) and feed when she wants to feed. Totally off the cuff, no rough routine or schedule. This seems fine as she is so little. However, there are a lot of folk (Gina Ford, Baby Whisperer advocates etc) who would say that as baby gets older this means that everything will be chaotic and they will have no chance of sleeping through the night as they will be all over the place! What are your thoughts? And if you agree with the HV, is there a point where I should start to introduce more of a structure in order to get her sleeping more at night? Interested to hear everyone's thoughts!
