daytime napping

Woozer💜🤓 • Love being mummy to LB #1.

Hi......im currently trying to establish napping routines with baby. we are trying to get him to settle for daytime naps in his own room and cot rather than being held. We have successfully managed to get him to sleep in there but will only sleep for 45 minutes....then wakes up and falls back to sleep once downstairs in my arms. How can I get him to sleep longer in his own bed??? Any advice much appreciated!!!!
