I also fully think she was letting him run amock and endangering babies in the baby area used to drive me insane as like others say it’s always those parents who aren’t paying attention or won’t say no to their kids. If I didn’t give my 4 year old a countdown when we are leaving what we are doing she’d probably kick off at leaving places but there are ways to help. I get the feeling she blames everything on ‘boisterous boy’ behaviour.
