My 9 week old girl used to sleep with me, but 2 weeks ago I started to put her into her cot for nite, she sleeps there for 4-5hrs, then she is up for feed and then she sleeps 3 more hrs if I'm lucky. Also she won't take day naps in her cot, only in her swing or in her pram. How can I help her to sleep longer during nite and have naps in her bed during day too? Thanks
