Baby sleep: probably the most talked about, confusing, troubling, and tiresome (wink wink) aspect of parenting a baby. With Isabelle we had a pretty rough first year and half with regards to her sleep. From about 4 months until 8 months she went from waking only a few times a night to waking up every 45 minutes. Every 45 minutes. For four long and painful months. (Hello zombie parents.) Then she started sleeping through the night for a few months. Following by lots of travelling and moving back to Canada which put us back to square one. At about 1 1/2 she started sleeping through the night again and, at 2, was able to put herself to sleep on her own.
