Can we make it?

Recently stayed at home and my mum is damn kpo kind, like to help out neighbors. And so I gained some babysitting experience and made me think what kind of age gaps I would want my kids to be:

1) 7 year old, 18 months and newborn
Have to entertain the 7 year old by talking to her intelligently, then 18 month old walked around ALOT, so have to make sure he don't go to the kitchen or worse, throw whatever he has on hand at the newborn!

The chaos came ard 11 plus where all need to be fed with different kind of food, the 7 y o need to be prepared for school (tie hair, keep the toys, wear shoes etc), 18 month old may be cranky without napping.

2) 18 months, 2 mth and newborn
The 2 mth old yearned for a lot of attention because she was so used to it. So you can't really leave her alone for a few mins even. She need to be carried or rock to sleep.

On top of that, while bathing the 18 month old, 2 mth screams on top of her lungs for attention, then newborn may be crying for food.

All these are on top of a dog who feels so lonely and want attention too.

Well, I am still inclined to keeping the age gap close first. I guess when the going gets tough, the tough gets going.
