Having a baby together should bring couples together. But in some cases it could actually be driving them apart, according to a new study.
A survey of 2,000 parents found that 30 percent of those who had divorced or separated blamed it on sleepless nights cause by their children.
Eleven percent even admitted to pretending to be asleep when their child woke up so their partner would have to deal with them.
Parents with a young child get about six hours of sleep a night, which is one less than the recommended amount.
