On which day is ideal to bath a newborn? mydaughter is now7days old, is it ok?can we use soap?

NO ideal day: Baby this age does not need a bath every day...Every other day should beadequate and short sponge-baths should do, and you may use mild baby shampoo/soap...Very little is needed. Make sure you test the water on sensitive area of your skin...I.E. The inner forearm area to make sure it is not too hot/cold etc... When in doubt, consult doc...Ask questions during baby visits. Best of luck.

Parent choice: Newborns typically get their first bath in the nursery. After that bathe them every few days as needed. Be sure to allow skin folds (ie neck) to dry. Until the cord falls off do not submerge in water, just sponge off. Frequent bathing with soap can dry the skin. Use a mild (no fragrances or colorings) soap or just use water if they soil often with spit up or poop.
