Regression takeover or whatever is is

These past couple days/weeks since Mason has been born, Kaitlyn has been in regression mode - pacifier, wanting to be held, still holding the breast for comfort and sleep. however, she has been eating at her kid table, helping mama out a little with mason by picking up after herself - in a way (takes her awhile especially if watching tv). need to figure out how to get back out of this rut - hoping it's just another phase again now that Mason is around.
