It depends on a number of factors:
On average, typically, one tin/jar of baby food can cost around 50p to £2.50 ($1-$4USD), depending on the above factors.
well it depends on how much you feed you baby
A baby sitter usually cost 3-10 dollars an hour
If you get the average baby food, one would cost around $.98 so if you multiply that my 500, then 500 jars of baby food would cost $490
$1.50
7000,000,000,000,000,000,000,000,000,1 dollars dumb a**
Baby shampoo start out costing about 3 dollars a bottle. The best baby shampoos can cost as much as 10 or 12 dollars a bottle.
That would depend on where it was sold.
They are usually around 50 to 100 dollars at least.
IM not sure about the collection, but for a single chapstick it will usually cost about $2.50 to $3.00
Depends on how much your baby needs. If he is fat or "extremely large" he requires a bit more food and drink, etc. and if he is skinny or "extremely thin" he requires less food and drink, etc.
they drink water and they eat regular dog food
This depends on the baby, and the food. A baby is different in terms of how much it can it, and how frequently you feed them. It also depends where you get it. If you feed the baby 2 times a day, it could cost roughly 120 dollars. 150 at the max.
