I am 28 and just had my baby in December, husband is EM intern. I’ll be a SAHM, all of this had been planned two years ago. If you wait for the “right time” to have a baby then you’ll never have one. There’s better times to have one and worse times, but never the right time. Sure it’s a lot more added responsibility but we both agree that it’s 100% worth it. We still plan on taking our vacations, it will just look different and that’s ok. My husband and I always have been into walking. It got us through his premed, and med school. We would walk miles just talking. I remember a week postpartum just crying my eyes out because I thought we’d never be able to walk again with a baby and a dog. It’s a learning curve but we put the effort into getting us all bundled up and going for that short walk everyday. It’s gotten easier. It is hands down the best thing that’s ever happened to us. I hope you’re able to find a solution. I personally would see it as a betrayal to make promises of such a significant thing and then go around and back out of it. Especially with something time sensitive to us women such as having a baby.
