Our moms and grandmothers often have some of the best advice when it comes to parenting and sleep. So, if possible, go talk to them. See what wisdom they have to offer. They may know a lot more than you think!
I was looking through some photos and I found these of my own mom from around 1944. Cool huh. I love the bonnet!
When asking for advice, it is a good idea to have some general knowledge, especially about current safety recommendations. As great as their advice often is, sometimes it isn't the safest and sometimes it goes against what you have learned to be true (i.e. a common myth I hear is to keep kids up longer to get them to sleep longer when the opposite is true).
