nap routine with an older sibling

[moojie]

Ds2 is 7 months and we have never really had a routine and he has seemed fine with this until now. He is demand breastfed but usually goes 4 hrs or so now he is on solids. Sleeps well at night usually.

I have a 3yr old ds too so not always possible to stay in a nap time. Because of the nursery run at 9am then 12pm then some days 3pm I'm often having to wake him. He will only sleep 30 mins in the car seat even if the car is moving. I have to drive to nursery so buggy not an option.

How did you manage the younger childs naps?
