Swings

Does anyone's 6 month old still use the swing? My son has been waking up around 3 every night and I put him in the swing till about 6 because he won't doesn't want me to rock him. I feel bad for doing that but I am so tired I have a full time job and so does my husband and we have a 3 yr old also. I know he can't be in the swing forever when he wakes up at night. He also has a problem keeping the pacifier in his mouth. He wants it but doesn't keep it in. He sleeps with his receiving blanket holding his paci because there isn't any other way he will keep it. :(
