Under California law a chemical test that is acquired within three hours of the time of driving is presumptive of the blood alcohol concentration at the time of driving. There are many ways that a lawyer can rebut the presumption, one (or more) of these ways may be applicable to the facts in your case. You should contact a DUI defense attorney and discuss the facts of your case and the possible defense and outcomes. In California, child endangerment is a very serious charge but can often be defeated in the context of a DUI by a competent DUI defense attorney.
