my baby girl is 8 months old. She has been full time at nursery for 1.5months and I have been asked to agree to move her on the mat to sleep. I am very concerned about this, as she isn't a good sleeper for a start. Secondly, could it be harmful for her physical development? Thirdly, can I refuse to have her moved to the mat on the floor? Lastly, what is a recommended age for a child to nap in a cot? many thanks
