wow, i am glad you found WIM! I went back to work when my son was TWO MONTHS OLD! All your Facebook friends would probably faint. And, when i went back, we didn't have daycare yet so my husband stayed home for 3 weeks until daycare had availability. Our son is now 4 and smart, happy, well adjusted, and love his parents to pieces (as we love him more than anything as well!). Staying home does not = love just like working does not = love. Only love = love.
Every family is different and you make your decisions based on the needs and requirements for YOUR family. If their families require mom to stay home and not work, that's fine! If you need to go into work and stimulate your mind and provide a portion of income to your family than DO IT! and be proud of your decisions.
There are likely other young couples, and even some moms there that may be looking to you as a leader and a role model. You never know the positive impact you have on those around you, so don't let a few naysayers talk you out of what you know in your gut is the right thing for your family, you may just end up inspiring other women leaders in your community
