A child never having a tantrum is not always a parenting related issues.
Child 1, rarely did
Child 2, did through frustration as couldn't speak
Child 3 an angel till hit age 5, then discovered her dramatic side
Child 4 OMG, never turn your back on her. Stubborn, and never forgets.
Child 5, sweet natured but more likely to pout and sulk at you
Child 6, only 8months old, no tantrums yet
We rarely use a high hair past the age of 1 or when they can safely SIT on a chair. Chairs aren't for standing on. Bums on seat, not feet.
One was potty trained at 4 years as she refused, earliest one was just age 2.
One could walk miles, one cannot due to mobility issues.
I have three of buggy using age, I generally sling one, have one in the buggy and a spare seat for the walking child for moments of tiredness, or unsafe areas of walking. We don't drive, go everywhere on foot. I always have a spare sling with me as well, in case two need to be carried.
I am very child led, but love and respect for each other is upmost. As is safety.
