Hi mummy. I think spending such a long time outside is quite a shock for him and even more so if he is unable to get his naps in time - they will be overtired and cranky. When go out, they like to ok at things and lights and all the sounds and all are very stimulating for them so it will tier them out even faster. IF u only intend to use a stroller, pls ensure that it is comfy (has the infant inserts/cushioning) and have the stroller facing u. Practically speaking, u should really just babywearing ur child in a ringsling (most comfortable) or wrap (next in line) or a carrier. Baby can be kept close to u and the warmth and sense of security will help them calm down, u walking around and talking to them so closely will help them fall asleep.
Don't give up. Join and discover the wonders of babywearing - it will make ur life so much easier - calmer baby, save ur hands too, baby can sleep in it too
