As a word of warning to all new mums and mums to be please do not under any circumstances ignore post partum shakes. I had shakes from day 3 up till day 7. On day 7 I caved in called the hospital and was admitted with severe septicaemia. I was told if I had left it one more day I might have died. My temperature on admission was 41.3 a degree away from seizures. I was told each time my midwife visited it was hormones from my milk coming in making me shake and that it was nothing to worry about. I only called on the 7th day because my milk came in and nothing changed. Always phone for a second opinion, it does no harm.
