Does anyone else have a fight to brush their LO's teeth?? Its such a fight morning & night here brushing Akaila's teeth & I'm starting to get so tired of it.

She has 4 bottom & 4 top teeth and she is not to bad with me brushing the bottoms but when it comes to the top ones she clenches her top lip hard against her teeth so I can't get to them. Then its a screaming match trying to get the tooth brush or clean face washer in her mouth. Any body have any ideas on ANYTHING I could try????
