is itnormal that the 4.5 month old baby taking a break ( about 10 days) after rolling over 3 times by her self? she rolled over by herself about 3 times after that she is not is it normal?

A. Some succeed, but most take another month or two. By 4 months , many babies can roll from their stomachs to their backs. At 6 months, many babies begin rolling from their backs to their stomachs. If a baby cannot roll in either direction by 6 months, it may indicate a developmental delay or underlying health issue.
