Lisa - we had this problem too with DD1 and I had severe SPD which meant I couldn't lift her. She wouldn't stay in the stroller, wouldn't hold hands and would run off. So we had to use a harness. I don't think there's any hard and fast solutions - just do what you think best and know that he will get a lot better when he's older.

DD2 actually likes being in the stroller and I can't believe what a difference that's made. We can actually go out without it being a hugely stressful experience. I do remember those times with DD1 but like I said before, he will get better eventually, I promise.
