The breastfeeding rhythm keeps on changing as the baby develops; sometimes she wants to be fed more often and sometimes less often.
It is normal for your baby to want to be fed 8 to 12 times within 24 hours from the first day onwards. In the first few weeks of life this means breastfeeding at night as well. In this period there are phases, especially during the evening, in which your baby wants to be fed hourly (cluster feeding). This is absolutely normal. Her feeding rhythm also speeds up during growth spurts. After a few days your breasts and their milk supply will adjust to the increased demand.
