My aunt, who reared ten children and at one time had five children under four years of age (including 2 yr old twins) has just spent a day minding her first grandchild and said it was harder work than anything she had experienced before. The baby came with a list of instructions as long as your arm, a huge bag full of lotion for this and ointment for that, a rigid timetable of naps and snacks and drinks, rules about sterilising anything the child looked at, and complicated sleeping bags and play suits to be zipped in and out of.
I have seen this with a few friends as well - they can't meet you for lunch until 2.30 because the baby has to be fed at 1.28 on the dot, no one can visit between 3.00 and 4.30 because that's nap time and the baby will wake up at the slightest noise, are constantly pulling things out of their baby's hands because of 'germs' etc etc etc.
AIBU to think some mums just go over the top, obsess about every detail of rearing a child. and are turning it into an overly complicated science when previous generations managed perfectly well without half of the nonsense some modern parents go on with?
