My 6 month old lb doesn't have a set nap schedule - I put him down based on his last wake up / when he looks tired and he sleeps between 45 - 90 minutes usually. As such every day is different and I don't know when he will be napping. I'm sure I'm not the only one in this kind of 'routine' so what do people do when they have places to be like swimming lessons etc? Do you skip a lesson or wake baby up?
