We have a rough routine with our 5 month old DD where we will try and put her down for a nap after approx 2 hrs of awake time but when we're out it's a little harder as she's so nosey and loves looking around.
DP is taking her out for the day on Saturday with some friends to give me a day of peace and quiet. He will be out from about 11am - 8pm. She will sleep in the car and in the pushchair when they're walking around but generally when we've been out before I'd say she is awake for longer than usual because she loves looking around and there's so much going on so it does keep her awake and she can end up getting a bit irritable until we manage to get her to sleep.
We have been for days out the 3 of us before lots of times but not for this length of time. I am a little worried about her getting overtired especially with the heat but don't know if i'm just overthinking things as I know he will take good care of her.
Surely one day won't hurt!
