My 6 mo. old baby girl has been a great sleeper since she was about 8 weeks and typically had at least a 7-9 hour stretch of sleep before waking to eat. Unfortunately, nursing has been very difficult for us and the past 6 months have included many nursing strikes in which we gave bottles of EBM. I also went back to work and pumped/gave bottles during that time as well. I happily quit my job to be home with my baby 2 weeks ago and since then nursing has improved dramatically. However, with that came a complete change in her sleep habits. She is now waking every 2-3 hours to nurse, which we haven't done since she was about 5-6 weeks. I'm fine with nursing at night, and am not trying to night wean, but, why the sudden change in sleep?
