Apollo Hospital — regarding blood sample collection in nicu

My daughter anahita (2years old) was advised to take thyroid test for blood sample was to be taken at nicu. Nurses advised me and my wife to wait outside. We requested that we will be accompanying with our daughter while collecting the sample but they refused to take inside. We waited around 15 min outside and the whole time we were able to hear crying of the baby. When after 15 min they took the sample and allowed us inside, we found lot of blood in the cotton. They told that first time the needle got out so blood has come. If they do these kind of mistake with my 2 year old baby, i cannot accept that. If they are not trained then they should in hired in nicu. They also not allowed either me or my wife to be inside for the whole 15 min. When they got out baby was shivering in fear which was unacceptable. For this i will also be filling complaint in consumer care.
