My nearly 4 year old won’t even try a scooter or a bike, is generally ok at walking but does have a buggy board on his baby siblings buggy. We’ve just come back from holiday and the entire two weeks was full of arguments over walking. Constantly saying his legs were tired and asking to be carried, we had many stand offs where we just wouldn’t go anywhere for ages or at all because he wouldn’t walk and we wouldn’t carry, he spent a lot of time on his dads shoulders as it was the only way we could get out and about most days. Is this a bit abnormal for his age? I see other kids younger than him on scooters and bikes and running around way more. He’s not overweight at all and when he wants to is more than capable. Is he lazy? Or is this within normal behaviour? I feel like I’m raising a lazy child and it must be my fault?
