We were in a pub at the weekend and sat beside a couple with a 2/3 year old girl in a pushchair.
Her parents tried to get her to go to sleep by covering the buggy with a blanket and rocking it but she was wide awake. She wasn't crying or cranky, she was just babbling away to herself and didn't really want to stay in the pushchair so they put her on a seat, put a massive pair of 'beats' type headphones on her, stuck a dummy in and plugged her into an iPad.
I fully appreciate its none of my business but it just made me sad that this was such an automatic reaction with a little girl who just wanted to interact rather than a last resort.
