How do I keep Grandma's help when we disagree about the baby's nap setup?
Parenting"She sleeps longer like this," my mother said. My three-month-old was on her tummy in the cot, with the blanket Mum had crocheted tucked around her.
I moved her onto her back and removed the blanket. We have a firm, flat mattress in a safety-approved cot, but Mum thinks my rules are stopping the baby from settling. She pointed out that she raised three children and sat in the room throughout the nap.
[CDC guidance applies back-sleeping and a firm, flat sleep surface to every sleep, including naps, and says to keep blankets and other soft bedding out](https://www.cdc.gov/sudden-infant-death/sleep-safely/). I'm following that. I need to work out whether Mum will follow it too.
She looks after the baby one morning a week while I work. When I said we couldn't repeat that nap setup, she heard that I thought she was a bad grandmother. Alternative childcare would cost more than I earn during those hours. How would you discuss the arrangement without turning appreciation for her help into permission to ignore the sleep plan?
