Wait til she's napping and then cut them...always worked well for me!
Old time trick was to bite them off, Yes I know it sounds odd but for an infant that is the safest way. Lots of stuff was done years ago we don't do today, belly bands for instance and sterilizing bottles and serving the formulae warm----My last baby got cold formula right out of the fridge as it was done at the hospital where she was born.
At a year or so parents put baby's in those baby shoes that were like work boots, when they kicked you ended up with black and blue bruises. After the shoes were outgrown off they went to be bronzed.
Baby's were placed on their stomach to sleep so if they burped up the stuff would not be inhaled and cause them to chock to death.
There was thinking of the day that if an infant cried at night to ignore it and let the baby cry itself to sleep. Some Doctors said that a parent could spoil an infant by picking it up and calming it.
The older generation was aghast at this thinking, if an infant was dry, and fed and it still cried, there was something it needed, be it having it clothing re arranged for comfort or perhaps it just needed to be held, or in pain.
The only time my Grandmother ever spoke a harsh word to me was one day when I was following advise and my 2 month old baby was crying. I had her in put down for a nap and she kept crying. I followed advice as I had been told to put the baby on a schedule and ignore her crys.
Full of piss and vinegar she went on a tirade about Dr. Spock and gave me an earfull.
Old time thinking from the turn of the century, one cannot SPOIL an infant, they only cry for hunger, being uncomfortable or pain. Spoiling comes about the time a baby turns 2 years of age when they first learn to manipulate their soundings and the people there in.
Today I am amazed at how infants and baby's are raised by people of other cultures. The parents may work but the infant is always in someones arms awake or asleep. It is rare that the child is not 6 inches from a care giver. The child may sleep with the parents until they are 3 or 4 years of age, that will be the first time they move on to their own space without the security of care givers.
A former cop once mentioned that the kids today are angry, mean and sullen, hate their parents and life in general. Well no wonder, they have no basis to trust anyone, have not the 3-4 years of security bonding to family. From the day they were born they had perhaps 3 hours total a day being in human contact with others.
Just a rant as I wish to heck I had followed my instincts and not listened to the so called experts that had the book learning but no hands on training.
