Bridal/Baby Shower

I was wondering what your thoughts were on this situation.

Jack and Jill live together, have a baby, buy a house. Jill has a nice baby shower.

A couple years later Jack and Jill plan a big wedding. Jill gets pregnant and they decide to make it a small wedding and get married in a few short weeks.

Three months later Jill wants another baby shower and the bridal shower she never had combined into one.

People are asked to bring a baby gift, a bridal gift or both.

People are invited to the combination shower even though they weren't invited to the wedding.

Is this proper to do a combination shower even though you normally only have one baby shower and a bridal shower three months after the wedding???

I'm Really Really wondering what your thoughts are on this situation.

What is the proper way to handle this situation? THANK YOU FOR YOUR TIME
