Hi, my DS normally a smiley, baby who goes to bed and follows a routine a night but has started having tantrums when I put him in his buggy. He cries 'til he falls asleep if he's tired or just cries 'til I pick him up. I've lasted 35 mins. He's not hungry, doesn't kick off at night in the cot or in the car seat just the buggy. Any suggestions welcome? I've tried toys, finger food and drinks.
