I used a playpen for my children born in the late 50s and early 60s. My second baby was born when my son was 11 months old. Baby girl was a cryer. cried all the time. First baby loved the playpen. He would play, drink his bottle and sleep there. Wake up and play some more. Sounds awful but it helped me through those first few months. Remember the old saying, "Better to be safe than sorry!" So true for us grand and great grandparents. My step daughter once told me that most children's accidents happen at their grandparents house. Nice! It didn't stop her from leaving her son with us for 5 or 6 weeks at the cabin. LOL. We need all the help we can get. Children and grandchildren and great grandchildren are such a blessing and having a safe place is such a comfort. My new great granddaughter is 5 months old and she already wants to jump out of my arms. Gonna be fun!!!
