Widow With Children Marry New Husband

If a Muslim widow with children takes on a husband, what is her responsibility on them?

We have the evidence of example from the grand teacher himself - Rasulullah SAW.

Rasulullah SAW married Umm Salmah RA who was a widow, and she had a child from her previous marriage. Rasulullah SAW showed care and love to the child. He also taught the child good manners.
