There's an old adage that a baby can sleep through the night once they double their birth weight. My other two had doubled theirs by 4 months.
Clarabee was a little slower. It took her NINE months, but she finally did it!
She now weighs 18 lbs.
And now she'll miraculously start sleeping through the night. Right? RIGHT????
In fairness my first two babies were much lighter at birth, 7 lb 6 oz, and 7 lb 14 oz respectively, so they only had to reach 15-16 lbs to double their weights.
However both Brielle and Hyrum weighed 18 lbs before they were 6 months old. Clara is my little petite baby, growing nice and slowly at her own pace. I just put away her 3-6 month clothes a bit ago. A tad surprising since she was so heavy when she was born! (a smidge under 9 pounds)
