DS is 7 months and is terrible at night. Used to be able to bf him to sleep then put him in cot (I know, I know) but now he will not stay settled in cot or if he eventually does it will be for absolute maximum of 2 hours but usually a couple of minutes maybe 10. He must've had about 3 hours sleep max last night. He also won't nap in his cot - has to be in pram or car. He doesn't always need bf back to sleep just wants cuddles and he sometimes let DP do it. Really at my wit's end with sleep deprivation and need a solution. Is a sleep consultant worth it? Not willing to leave him to cry himself to sleep beyond leaving for a couple of mins to see if he settles.
