i haven't read all the responses... but i started a similar thread to this not long ago, something about childcare and socialisation.... i too did some research and also read that kids only going one day wouldn't transition as well as others doing 2+ days etc etc... i have two retired parents who mind my dd (16 months) three days a week, i didn't actually NEED to use childcare, but i just thought dd would maybe benefit from going...

in the end i decided against it, after dd getting sick after EVERY session at playgroup, i just thought how much worse it would be at childcare.... also i found some interesting material opposing parents trying to 'socialise' their babies through childcare.... it gave me a lot to think about and i decided she was too young for me to be expecting her to be 'social', IYKWIM.... we go to playgroup reasonably regularly, and she has gone from being a clingy baby, to a pretty well adjusted toddler running about playing...

if you google childcare for socialisation etc you might find the stuff i came across... it was dead against it in babies this young (for the reason of clingy-ness/socialisation).... anyways obviously if you NEED childcare thats a different story... i know lots of kids thrive in childcare and have nothing against it, and maybe one day dd will go when she is older, but i think its important its used for the right reasons - you're little girl is clingy cos she wants her mum, thats perfect natural and normal, give her a couple of months she might surprise you and come out of her shell..... is there a playgroup you can go to? i found the difference between my dd from say 13 months, to 15 months HUGELY significant - she really came into her own.

anyways good luck im sure you'll work out whats best for you xx
