Sleep after 12 months.

Sorry first post and I'm curious. When my daughter was born she slept for 5 hours at a time. So id get a total of 10 hours sleep a night. By 4 months that stopped, and she was waking every 3 hours and I was down to 9 hours sleep total. People told me it would improve by the time she turned 1. She is now 16 months old and for the past 4 months has been only sleeping for 1 hour at a time, so I get maybe 4 hours sleep total. I'm suffering, my work performance is suffering, and my relationship with both my daughter and her father are suffering.I'm curious as to whether or not anyone else's 1 year olds have this same issue? Is there anything I can do to improve it? via /r/Parenting http://ift.tt/2cTT0D8
