Attached already

Anyone else's little ones starting to get really attached? Dad or grandparents can put him down with no problem but when I try to he always puts up a huge fuss and I have a hard time getting him to sleep. Usually I end up having to rock him to sleep and then it's a struggle once I lay him down. Although I REALLY love the snuggles, I didn't think this would happen until later! He is 13 weeks this week.
