No, it does not mean the baby inherited more alleles from its mother. Each parent contributes exactly one allele for each gene. The baby looks like its mother because the dominant allele (H) for hair is expressed in the phenotype, even if only one copy is inherited. Since the mother is heterozygous (Hh), the baby could have inherited either H or h from her; if it inherited H, it will be hairy regardless of which allele it got from the father. Appearance is determined by which alleles are dominant and recessive, not by the quantity inherited from each parent.
