Does this seem mad? I'm going back to uni to retrain from September so DH will be picking up more nursery drop offs to accommodate early lectures and placements. Current nursery opens at 8, but DH needs to be at work by then so won't work. DD will be starting school when I start nursery so isn't a problem, but DS will be around 18 months so still have some time to go. He's due to start nursery in the spring, would you send him with his big sister until September (mixed age setting so would be in together) and then move him in September to another nursery that opens at 7.30, or would you suck it up for 6 months and do 2 nursery runs so he starts off and settles in to the nursery that will be where be stays and let DD finish off her time at her existing nursery before school?
