My dd often struggles to get to sleep at night, she can't seem to get comfortable. She sleeps on her tummy with her bum in the air and it looks really awkward. My sil suggested a pillow, her dd was the same and it helped.
So I bought one from mothercare but am now having doubts as dd is only 10 months. Am scared it's a big risk. Never had this issue with Ds, he slept happily on his side.
