I have a lovely 7 week old, slightly unexpectedly, and 3 others aged 6,8 and 10. Baby seems constantly exhausted, and will only settle when juggling in front carrier, and still feeding ++ at night. I am exhausted and overwhelmed constantly. My parents are helping out where they can, husband works long hours, and the demands all feel too much. I know it will get easier, but can anyone who has been there reassure me!!
