What is periodicity in maths with example? Periodicity is the tendency of a function to repeat itself in a regular pattern at established intervals. All trigonometric functions have periodicity. For a function f(x) to be periodic, it must have a consistent repetition of values of f(x) over the entire domain of the function.
Can you mix normal formula with hungry baby? Mixing will mean having 2 tins of milk powder open at the same time. The powder is no longer sterile once the tin is opened so it is important to use the formula within a reasonably short time. For this reason it would be best to use the normal formula up and then switch to the hungry baby formula completely.
How do I know if my formula fed baby is still hungry? “A baby will search for the nipple as an instinct, so if you hold him on your shoulder and he continues to ‘peck’ your shoulder or lean down to your breast, he’s likely still hungry.
