[R] lme4 help pls!

[xy]

Hi,
I have some difficulties to work with the function lmer from lme4. My
responses are binary form  and i want to use forward selection to my 12
covariates but i dont know how can I choose them based on deviance. Can
someone pls give me a example so i can apply. For example my covariates are
gestation,smoking ...and my response baby

b1=lmer(baby~ (1|id), data, binomial)

Thanks.
