We don't have a set routine with sleep and nap, just approximate times when we could expect her to sleep.
Do you strictly follow your routine? Try to schedule around it if possible? My mother teases me with now both my children because I make sure they always get the naps in.
Grocery shopping? After 10 or 11 am when LO wakes from nap. Both kids are/were inconsolable nightmares without nap. Crying for who knows how long until they fall asleep from exhausting themselves (nothing helps, breastfeeding, dark room, warm bath, etc). They don't sleep in the car or while out-- they're busy watching the world.
So I always avoid the crying and am fine waiting an hour to do stuff outside the house. But it seems to be inconvenient for everyone I do this 😓
