Litters can be quite large (up to 15 babies per litter), but the average size is only seven or eight babies.Of these, only five or six are likely to survive to maturity.fter conception occurs, gestation usually lasts 45 days. On average, mother squirrels welcome two to three babies, but she can have up to seven babies in a single litter. Typically, only one litter of babies is born to a mother fox squirrel per year.
