I totally agree with the OP.
When I had my first child, going away/eating late in restaurants/sleeping in her buggy while we chilled out, all worked out just fine. She was and still is a very laid back little girl who enjoys looking around, has the ability to sit down and chat and is lovely company
Roll on second child and going away is my idea of a nightmare. There is no way DC2 will sit in the buggy, sit calmly in restaurants until we are finished or sleep in the buggy. The only place DC2 will sleep is in the carseat or cot. Instead we are treated to tantrums due to exhaustion, screaming, throwing, screeching. We still persist in trying to eat at restaurants here at home (for otherwise how will DC2 learn?) but we limit it to places like M&S restaurants, Carluccios, Pizza Express - basically places that are child friendly and don't object when we ask for our starters and main courses to arrive at speed! Not only is the experience not particularly nice but it can be actually unpleasant and I am often very embarrassed when I look behind me when leaving a restaurant to see the mess we have left behind despite my efforts to tidy it up as well as I can.
Going away - the horror of applying suncream twenty times a day, the heat which makes DC2 crankier at home when it is not very hot at all. Apartments are up flights of stairs, not buggy friendly, balconies, pools..... I look at people booking holidays and feel relief that it isn't us.
DH on the other hand has visions of the children building sandcastles on the beach while he reads his book. It makes me snort with laughter.
