I expect many of us can recall at times feeling exhausted and exasperated by the demands of looking after young children - and I certainly wouldn't blame anyone for needing a little "me time". But I would have thought that, after having three children, this person would be aware of what parenting involves - and "me time" is usually in short supply. If this person had felt it unduly demanding of her time and energy (and could not enlist more help from the father who doesn't appear to be mentioned in the article), it might have been better to have limited her family, rather than make a conscious decision to add to it.
This little girl has just turned four, is still in nappies and needs the comfort of a dummy. Some children may be ready for full-time school at this age but it seems that this little girl isn't.
Let's hope this child never reads the article when she is older. Apart from it being, I think, rather hurtful it will provide her with ready-made ammunition (which it may be difficult for her parents to defend themselves against) for any wayward teenage behaviour.
