DS is 3y4m. We also have DD, 9m. I'm a SAHP, so with DS most of the time, though he also goes to Playgroup 2 mornings a week (and enjoys it).
He is great when he's with me and DD. He's great when he's with DH. He's great when he's with my mum. However, if he's with me and DH, or me and my mum, he whines, tantrums, refuses to do what he's told - basically anything he can do to be awkward.
My guess is that it's an attention-seeking thing - he doesn't like me being with other adults, and talking to them instead of him.
I just don't know what to do, though. Any family trip out is tiring, as he constantly whines, pulls my hand, and refuses to cooperate. It's worse if he's tired or hungry, but can happen any time.
Any suggestions?
