Imogen generally is a really independant little girl but since March time she's got really clingy, I decided it was just a phase probs brought on by the changes - moving, preg etc. She's just starting to come out the phase now, altho probably with Josh's birth she'll get clingy again.
I do a lot of reassuring with her, and pre warning, like if I need the loo I'll be really direct and say 'Imogen Mummy is going to go have a wee, will you be ok here?' or 'Immi, Mummy's going to get a drink, can you wait here' etc and I always make sure I get an 'ok Mum' before I leave. This seems to work well as she always feels reassured about where I am and a bit in control I guess.
