My 3 show the most affection when we go to bed....They snuggle on my neck and under my armpit...I stroke them and talk sweet to them and tell them how much mommy loves them....By the middle of the night they are wedged up against me so tight, I can't move and wake up with such aches and pains.....But I'll do it again tonight just to have the cuddle...During the day , they are very independent and sometimes won't let me even pick them up....They want their space ??
Although they will play catch and tug of war with me and eachother...Keep doing what you're doing, it sounds like it'll happen in time...
