I m still breastfeeding my 9 month old son, but ever since hes been born I ve had trouble sleeping at night - can t seem to switch off & when I do its only for a hour or so. I m absolutely exhausted. I ve tried exercise, no caffine, milky drinks, lavender baths, massage & nothing is working & the situation getting worse. Can I take any sleeping tablets short term? I still feed once during the night?
