I think it's a personal thing. If you wish your husband or other people to look at you the way they used to, you might not wait until your baby is seven. Just try and combine the both together, I don't really think that motherhood actually changes the dress code of a woman. Looking good and sexy and living the outside life is a personal choice you make.

My elder sister is a mum of four and is breastfeeding a baby right now but that doesn't stop her from looking good when she goes to her office or looking sexy for her husband.

As for stretch marks, there are creams that can reduce them. You may ask around your locality and buy one for yourself.

Being a mom is not that easy but as a woman, you need to package yourself most especially so that you don't loose your husband to another woman or loose your relationship with people because nobody wants to be identified with someone who doesn't look presentable.

I really admire your being realistic.
