Hi J.! I had/ have the same situation with my daughter ( age 3). We went through a series of events, including travel, company in town, and her getting sick, that all ended up with her sleeping in bed with us. She REALLY liked it. Before that, I was adamant that she not co-sleep with us. After all of those situations, she really wanted to just move into our room. My husband and I spent a few months of struggling with her. She would get out of bed multiple times, trying to get into our bed. It was to the point that she didn't even want to fall asleep in her bed. She said she was lonely, and just wanted to be in our bed, even if we went there. The situation was really cutting into my husband and mines alone time at night...and after a while, we just kind of realized that maybe we were fighting something that really wasn't a big deal. If it meant getting her to sleep easily, and giving us more time together, then why not? You know what...it has become a wonderful thing for our family. My husband and I both really enjoy the extra snuggles with her...and it actually allows me a little more sleep time in the morning, as she is so content to be snuggled up with me. For a while, she was hardcore about sleeping in our bed ALL the time, but totally on her own, she has weaned herself from it. She still comes in every night/ morning..and sometimes it is 11pm, but sometimes it is 7 am. Often it is around 2 am..and she slips in so easily, that we really don't even wake up. So, I guess the point to my super long winded story, is maybe see if this is really a fight worth fighting. If your son feels safe with you, why not? He will be at an age, before you know it, that he will want you to drop him off down the street, so his friends don't see you dropping him off...so why not take this time to really enjoy this close bond??
