contra it is sad, yes, but it is good that you are now thinking of how to prevent it. Youngsters and grown-ups can die in such unbelievable and easily preventable ways, like the tots with the chest of drawers, window blinds, marshmallows, there was even a fella who fell into his airer and got caught up and was suffocated. Life is fragile, so we need to enjoy every precious moment.
I have faith in the sleeping bags. I think they are the safest way, especially when a baby is mobile. Blankets were mentioned with little Matilda Mae, and the fact that she was crawling increased the risk. Thankfully it is very rare. We would have all been born before gro bags and we survived.
I am removing the bumpers today because of that blog, as even though he is not mobile, he might decide to roll in the night.
We cannot protect our babies 24/7 but we can do our best to limit risks. Maybe another baby will be saved because of that blog.
