Anyone any advice for dealing with a lo who has temper tantrums way before the terrible twos?! He sleeps and eats well, but hates going in the buggy (would rather walk, as he can do if he holds on to my hands) and sometimes car seat. Rigid body and lots of shouting. Am I making it wose by allowing him to walk when he kicks up a fuss, or are they too young at this age to learn about manipulation?
