Just looking for reassurance really. Eight week old had first immunisations today and at first slept a bit, then screamed the house down and had big swollen thigh, she then filled her nappy to overflowing and after changing continued screaming until she threw up over me then suddenly fell asleep. Took her back to docs who said that the injection had gone into muscle which sometimes happens and should be fine. Since then she's slept for about four hours, fed briefly then asleep again for another couple. Is lots of sleeping normal after injections - she's alert when she wakes - but not for long.
