Finding high-quality infant care continues to be challenging for many families. Such challenges are even greater for single mothers with limited resources and English language skills. Several years ago, this challenge formed the basis for an urban, center-based program called the Pregnant-Mothers Support Group (PSG). The PSG served single, pregnant women with low incomes who met Early Head Start eligibility criteria and needed infant care for their soon-to-be-born babies. The PSG provided a unique opportunity for pregnant women to explore some of these issues for themselves within a supportive setting. This article discusses how PSG provided opportunities for mothers to share information and build support systems and networks with each other and how attending the meetings helped mothers learn, strengthen, practice, and apply interpersonal skills in their everyday lives.
