Flat, collage-like illustrations in textured, blanket-soft areas of color depict a toddler watching and helping his/her parents care for an infant, each activity captioned with the phrase ``A baby to...,'' and ending with a different verb: ``love''; ``touch''; ``wash''; ``hold''; ``feed'' (this one is breast-fed); etc. The father is shown caring for the baby as often as the mother; the family is generically dark, but not very dark, while the baby has blue eyes. Falwell's compositions enfold the rounded figures in all the security of a happy family. An inviting concept book that should find a warm welcome in many newly expanded families. (Picture book. 1-4)
