At seven months old, they don't understand the word or the concept of spoiled. They need attention, not necessarily from just Mommy. Get Daddy involved in attention. Have him wear the baby sling and just walk around with baby close to his heart.
As for the part about not giving the others attention? Well, your hubby knew this when he signed up for fatherhood, so if he isn't willing to help, well, he needs to learn. It's not much different than baby #1, only since your other baby is 2, you need to spend time. Perhaps a story time with baby in a swing facing you, and your other one in your lap?
For night time, as I've posted elsewhere, a radio with soft music(I find classical stations work well) playing in the room at night helps with relaxing, as does massaging lavender lotion onto baby(your two year old prolly will want in on this, so be prepared!) just before bedtime. My son perhaps didn't sleep through the night, but he slept longer than I was told he would.
I am also wondering, how much time have you spent on yourself Mama? If you are stressed out, baby can tell, and will cling to you to let you know how much he loves you, and that its alright.
Have Hubby take him for an hour or two(maybe around the 2 year old's naptime so he's only got one to deal with), and take a hot bubble bath, or a dime-store facial and a cuppa with a good book afterwards. If you have time to recharge, you will feel invigorated and will look at this whole scenario with a fresh perspective.
Take care Mama!
