Bottle amounts for daycare

Ashley&Scott

DS has been consistently finishing his 2oz bottles for the last 2 weeks. Usually at 1 feeding per day he'll take two bottles in at one feeding. 

I'm thinking of increasing the bottles to 2.5oz & then sending some smaller bottles that they can give if he's still hungry after the first bottle. (If I increase I do not want them to give two 2.5oz bottles back to back.)

I was thinking of sending 3- 2.5oz bottles & 2- 1oz bottles that they can give if he's still hungry after the first. I would label them so they know the 1oz bottles are only to be given if he's still hungry after he has 2.5oz.  What do you think?
