18 month Constantly wanting to be up!

[Tocka]

Hi all, I have a 18 month old little girl who came to us when she was 11 months. She is the most sociable little baby I’ve met and an absolute dream when I’m out with other people... however... when I’m in the house with her she wants to be held constantly. She must say ‘up’ 300 times a day! She won’t play alone even when I’m in the same room as her. If I get up to put the kettle on she wants to be held and has a proper meltdown when I explain why I can’t hold her. It even happens when I’m sat down with her on my lap.
This has been going on since we had her! She’s too busy to sit down and play with me on the floor and cries because she wants me to walk around with her in my arms! I have absolutely no idea what to do or how to tackle this behaviour. I have no doubt that this isn’t because she us adopted but wondered if anyone else had experience with this?

@FlatheadScrewdriver fab suggestions! Thank you! I do try and narrate as much as I can but will try your other ideas. Thanks

@bunting1000 she loves the garden. She’s an outdoors baby definitely! Never asks to be picked up when she’s playing outside. Or when there’s other children in the house because she’s being kept busy. I think she gets bored in the house to be honest with you! I take her to playgroups etc but with it being school holidays I’m finding it so much more tiring.

@Sizeofalentil interesting! Thank you!
