CC Ādi 13.111
nāma tāṅra ’sītā ṭhākurāṇī’
ācāryera ājñā pāñā, gela upahāra lañā,
It appears that Advaita Ācārya had two different houses, one at Śāntipura and one at Navadvīpa. When Lord Caitanya Mahāprabhu was born, Advaita Ācārya was residing not at His Navadvīpa house but at His Śāntipura house. Therefore, as formerly explained (text 99), from Advaita’s old paternal house (nijālaya) in Śāntipura, Sītā came to Navadvīpa to present gifts to the newborn child, Caitanya Mahāprabhu.
