Omg thats soo cute !!! I dont see anything wrong with it either my husband would be protective also and not want the animal to walk on it but if it doesn't hurt u...I think its cute when animals can sense that their owners r preggers
my dog does the same I think as long as it doesnt cause you pain or they are not too heavy you should be fine, but thats just my opinion
I'm 37+3 nd my animals still walk on my belly nd lay on it... The only time I push them off is if my two lil girl dogs start fightin over who gets to lay on me haha cuz they get jealous... But ny cats nd dogs all do it..
