Has any other cat owners had this ?

The past week I have woke up to my cat (13 months) laying on my stomach, he use to hate it on my stomach but now he’s laying there EVERY morning and pawing at it/ making biscuits/bread/ kneading it however you want to say it lol Any one else had this ? Other info -I have a 20 month old boy -me and my partner are ttc baby number 2 (have been trying for 16 months so far and am waiting to see if I get my period)
