Sugarmouse:I'm not sure whether it's a reaction because of my attention being taken from her as L wants constant feeding at the moment
Probably a both of both...
Louise (3 and 9 months) had a whole gang of imaginary friends, and it started when I was heavily pg. The most significant one was "Pretend Baby", who did awfully naughty things in our house (writing on walls, spilling things around "not by accident" etc). I am sure it was directly connected with the impending arriving of (not Pretend) Matthew!
I found it hard to discipline her, I didn't do much tbh. I was fed up once as she had done something and I saw her do it yet she was swearing she didn't, Curly did it. In the end someone told me that the best way to deal with it would be to discipline everyone in the house if somebody has done something wrong. So nobody got a treat (or whatever it was) as Curly had done something naughty.
It was quite funny at times though. The worst culprit was Pretend Baby, and there was Curly, Charlie, Nina,... And she acted disgusted when "they" had done something naughty (or "bold", as we are in Dublin!
)
She has grown out of it a bit since Matthew was born, she announced recently that Nina, Charlie and Pretend Baby had gone back to their mammy and daddy, in England (?).... Curly is still around though...
