I'm torn and in severe need of advice.....How can I help my baby go to sleep better?

I its time to try sleep training. Continue with your bed time routine, then just set him in his cot say nigh nigh etc. When he cries let him go for a few minutes, then go in, give him a little pat mummys here etc. Then in a firm voice say nigh nigh time and leave. This time if he cries leave him a few minutes longer etc. Its really important that you dont pick him up when you go into comfort him! If anyone tells you this harms babies its not true, i had to do this with my eldest. And she is the most loving affectionate child with no problems whatsoever! I know these times are hard but you will get through it!! All the best x x
