Hi, my 4 month old baby will only go to sleep around 12am midnight every night! She wakes up around 9.30am - 10.30am! Recently she's really hard to settle as she will cry as soon as we put her down in crib the rocking all night is tiring us both out! We have tried to put her to sleep earlier but she is not having none of it! I'm worried I have created a bad routine for her and struggling to get some sleep myself!
