Baby off schedule after errands

Ma

I’ve gone out twice this week during the day with my son and both times were a disaster. The first time I took him out as soon as he fell asleep for his morning nap, but he woke up as soon as I got him in the car and he stayed awake the entire time, so he missed out on his nap, making him super grumpy for the rest of the day, until he finally fell asleep around 11pm.

The second time I tried taking him out before he fell asleep for his nap, which was fine until we got home. After we got home (around 11am, nap time) he decided he didn’t want to take a nap until 3:00pm, which again threw off his whole evening routine and made him super grumpy. Not only does he get grumpy in the evenings when I take him out, but he also stops sleeping through the night! Usually he goes to sleep around 10 or 11pm and sleeps until 8:30 or 9am. This week he started waking up at 6:30am since I’ve been going on outings! I have lots of doctor appts to monitor my health after giving birth almost 3 months ago, so I need to be able to take him out sometimes, let alone normal grocery shopping.

How do you all manage to run errands without completely throwing off your baby’s schedule? Any advice would be appreciated!
