Yeah, I think its a cool post! Grandparents can learn the latest information on swaddling and safe sleep practices, as well as car seat safety. They can also get tips to help support their own children as they step into parenthood. Boot camps can help them talk on relationships and postpartum depression. It is very useful and grandparents will know the signs so that they can understand the different between baby blues and something more. PPD is a real problem and it is important that other family members know what it is and how to address it.
What I'd really like to see is interventions and programs geared towards those who support mothers, the spouse, grandparents etc. The mothers have so much pressure on them already they barely need more interventions telling them what to do. Its the people around them who need to be trained so that the mothers experience can be just about her baby.
