If you don't mind me asking (for clarification purposes)
How "old" are you?
Are you pregnant? Contemplating pregnancy? The mother of a baby/toddler?
Or is it just something someone said to make you feel this way?
Medically speaking, older mothers are classified as being 35+ (which, relatively speaking, isn't that "old"). They even have a special name for women in this category, "elderly primagravida"! Now that does make one feel positively geriatric!
Pregnancy/parenthood is tiring at any age.
I am a 44 (nearly 45) year old mother of 2 girls aged 2.5 and 6 months.
Some days are very tiring, especially when compounded by lack of sleep, but it gets easier.
I would be interested to readyour story.
