My 7 month old has been extremely loving and attached to me lately. I think he senses that I am pregnant. He rubs his little face on my belly and boobs he also cuddles with me a lot. He gets so upset when I leave the room and calls out to me. He sleeps with one hand and foot on me at all times. His dad works overnight so we've been co-sleeping a lot lately
