I'm having some major issues with getting my Children, 2&4, to sleep. The earliest they are both asleep is 11, but most nights my son is up until gone 1 some nights even 3. Then they will both be up at 7. This has been going on for months. I've stopped my son napping and we do plenty of activities during the day which should tire them out. My daughter used to sleep perfectly. I would put her in bed read a story and she would go straight to sleep. Me and my partner split up a year ago and I can't help but feel thats to blame. I'm completely out of ideas on how to settle them down and get them to sleep. Any advice would be really appreciated. Thanks in advance from one tired worn out mama!
