need help ladie

Since I started Olivia on solids she will not sleep through the night maybe an hour at the most and then she's awake for 3 then sleeps for another hour. I'm seriously knackered. I've tried giving her a bottle in her cot I've tried just giving her her dummy I've tried rocking her to sleep before putting her done but she won't stay asleep longer than an hour .. What to do ??
