I had 2 under 2 (17 months apart). Being pregnant and caring for another kiddo is a wild ride. My postpartum anxiety kicked in during the second and third trimester (worried about how we are physically going to do everything with 2 kids, day care, help from family, etc). I just talked to other friends that had 2 under 2 (I attempted to get into a PPA group, but everyone had a waiting list). It helped and I went to prenatal yoga (helped tremendously!) Yoga not only helped me get out of my head, but helped prepare my body for baby #2 & did some chiropractic work at the same time- game changer! If it's possible, try to make time for yourself whenever you can. Self care will make things feel better and might help you mentally. My kids are 2 years and 6 months now-- they have a great relationship and are starting to play with one another. It's a wild ride, but so worth it. You got this!!
My kiddos are just under 16 months apart. It is a wild ride for sure, and having 2 under 2 is hard, but oh so rewarding. Some of the positives to help ease your mind: they'll have no memories without their sibling, built in best friend. If you're done after 2 kids like I am, you go through diaper stages quickly, and then you don't have to worry about it later. The little moments now are my favorite things to see, like my almost 2 year old offering her snacks to her brother and wanting to play with him. It just warms the heart. I will say, as soon as you start showing with baby #2, start talking to your first about having another baby. Get them excited about having a sibling, it makes the transition easier
I haven't personally but my friends have 2 kids, one friend has a 1 and a half year old and a 9 month old and the other has a one and a half year old and a 7 month old. I don't know how they personally feel but they wouldn't change their situation. I'm sure some days are more chaotic than others but as they get older they'll have an amazing bond.
