Los Angeles, Feb 12 (IANS) Singer Peter Andre is struggling with a lack of sleep due to his 10-week-old son, Theodore.Andre says the disruption Theodore is causing to their household has come as a shock because his and wife Emily's three-year-old daughter Amelia was always a good sleeper, reports mirror.co.uk."Little Theo has had me up early every morning I know he's only 10 weeks old and a lot of people will probably say it's not unusual, but because Mills was sleeping through the night from six weeks I'm finding it particularly hard," Andre told new! magazine."As Emily is still breast feeding, I can't take over during the night so we do a deal where she goes to bed at 9 p.m. and I have him until midnight, and then at midnight she'll do a feed."Then I'll try and sleep between 12 and 6 a.m. and take him from 6 a.m. or whenever so Ems can catch up on her sleep. It's a bit mad at the moment but it's all done with love," he added.
