Can your dp/dh/father of your children look after them on his own? Two children aged 18 months and 4.5? Or just tow under 5. No additional needs or SEN.
If so for how long? What set up support would be needed if any? For example getting clothes out, sorting food etc. If he did look after them alone would he manage well or just cope?
Is this something which happens regularly in your home? Or would it be like you owed him something and he'd be a bit put out?
To be full transparent just having a conversation with a friend and she felt it's normal her dh can't really (doesn't want to) have the children on his own. When she is out of the house. I don't think this is normal and most fathers can do childcare independently even for pre school age. I look after the kids I know although I love them it's not easy!
I think she thinks what men can do and what they should ideally do are different. So is it unreasonable of me to think a father should look after two children that age? Not sure if I'm being unrealistic?
