Broadly speaking, there are 4 opportunities to photograph the babies in the first year of birth.
The first milestone is Newborn Photography. This happens in the first 30 days. However, the most ideal time is from 6 to 12 days of age.
The second milestone is Baby Photography. This happens between 3 and 6 months. The most preferred time for this type of shoot is 4 months.
The third milestone is Sitter Photography. This can happen as soon as the baby starts sitting without support for about 15 minutes. This can happen anytime from 7 to 16 months. However, the most ideal time is 8 months, just when the baby starts sitting but before they start crawling.
The fourth stage is Cake Smash Photography. This ideally should happens around 10 months but can happen anytime from 10 months to 18 months.
