But by yesterday Taylor had improved and was expected to be released from hospital today.
"Things are looking better, neuro doctor gave us good news, nothing bad with her brain. Waiting for main doctor now. Could be home time soon!"
Weepu's partner Candice Russell posted pictures on Facebook from Wellington Hospital, calling Taylor 'Our tough little cookie'.
It was the second health scare to hit the Weepus this week after Taylor's sister Keira also had seizures, prompting neurological tests in hospital for her too.
Former Waikato Hospital director of neurosurgery Venkat Balakrishnan said the brain scans were usually ordered to check for conditions such as general epilepsy, focal epilepsy, drop attacks and brain tumours.
"Children with epilepsy require careful watch and observation, checking the pattern and progression of epilepsy, checking the effects of medications [and] its side effects to check which is the best drug to control their epilepsy."
Balakrishnan also said parents of children with epilepsy should take special care - though there was no confirmation the Weepu children were suffering from the ailment.
Epilepsy campaigner Amie Jane, wife of Weepu's All Black teammate Cory, voiced her support yesterday. Their son Cassius suffers from epilepsy.
Jane Tweeted: "Poor baby! We love u n Cass knows how it feels pretty girl xxxx"
Last month, images of Weepu bottle-feeding Taylor were cut after protests by the La Leche League, sparking a nationwide debate about breastfeeding.
