DD eats what we do - again, it's just a fact. Nothing to do with being smug but because she will chuck an absolute shit fit if she is given something different to everyone else and will point blank refuse to eat it. I do cook from scratch, but only because I enjoy it and find it to be cheaper.
Plus side is leftovers get frozen so on the days where DH and I eat later (he works late so I usually have my dinner with DD as she doesn't eat as well if I'm not eating too) there is a family dinner for her to have.
She slept through from five weeks - but also had severe reflux with projectile vomiting until she was 10 months, and still occasionally hurls at 16 months.
She's been having epic tantrums since she turned one, and when her nappy is wet she strips off her bottom half, removes it and waves it around. No matter where we are not helpful.
Add to that the fact that she was on a monitor from birth to ten months for being at a higher risk of SIDS.
I honestly believe that we all get a pretty fair share of easy and hard bits with our children - it's just which are which differ from child to child.
Mine eats and sleeps, which is my easy - but then I have my hard in that she also was the sickiest, most colicky baby I have ever come across and made mountains of laundry (think one outfit, one bib and two muslins for every single feed) and resulted in me spot cleaning the carpets on a daily basis, plus the monitor, tantrums etc.
So whilst you might feel some people are smug for stating facts that their children eat and/or sleep - bear in mind that there will be things they find incredibly difficult, just as you will find other things no bother at all.
I am not smug - but I am pleased that she eats and sleeps - because if she didn't on top of all the other stuff I'd be destroyed!
