My son lives with me, but stays with his Dad 2 to 3 nights a week depending on EH work schedule. I am currently not working due to ill health and am in receipt of benefits for myself and also my son - child tax credits, child benefit etc. Can my benefits be affected by how many nights my son stays out? I was under the impression that as long as I am the only person claiming for him, how often he 'stays out' isn't an issue, however I just wanted to check this is the case as EH is asking if he can stay more in the school holidays.
