Thanks everyone glad to know it does pass.
I was speaking to a mum today and she told me not to fight it just give her what she needs because fighting it will only make it last longer. She also said to establish a verbal routine everytime i leave her even to go to the loo - so say "mummy is just going to the loo i will be right back" then when i come back say a similar thing only "mummy is back now from..... eventually she will realise i do come back.
Its so tuff being so needed, but i have to say there are a few moments when it makes me feel like the most special person in the entire world. AHHHHHHHH!!! Not looking foward to having to beg for cuddles. lol
