Your wife has changed since taking on the role of motherhood. You yourself while trying to accept these changes have had a hard time adjusting to some of them. She will also learn to accept and adjust. You have had 4 years to do so she has had a few weeks you might just want to give her a little time.

I was referring to the amount of time you have had to accept and adjust to the changes in her since she has taken on the role of motherhood vs the amount of time that she has had to adjust and accept the changes within you.
And trying to point out she may need some more time.
