Couple of questions Amy - those are quite mature trees and therefore can be difficult to get established. I think they're suffering a bit from transplant shock
How are they planted? It's hard to see from your photos, but they seem to be in your lawn. Have you dug out a decent area of grass to plant them in? That's vital to give them a good chance. The grass will compete for water and nutrients. They would have needed some compost/well rotted manure etc dug in to the soil too.
Have you staked them properly? That's important too or they'll be damaged as soon as autumn/winter comes.
Trees that size will need a large amount of water regularly as there's a lot of top growth to support. Watering lightly every day is no good as it encourages the roots to go up, instead of down, in search of moisture. A few gallons every few days, (depending on your soil conditions) is the way to go. It's often a good idea to sink a bit of pipe down the side of the planting hole with the top exposed, so that you can water into that and sent it down to the roots. A layer of mulch on top of the soil round the trunk will help preserve that moisture too.
