Are we crazy to want to start trying for baby # 2? We had our little boy in mid-January but my husband is deploying in June and we want our kids close in age... I also loved being pregnant and miss it, plus we both have been really wanting another baby since our little one is absolutely amazing 😊 if we do start trying again, how will I know I'm pregnant if it's before my first Postpartum period?
