@markrhoward Hello! You've received a lot of great feedback here already so I will try my best not to repeat a lot of what has already been said.
I just had my second baby 3 weeks ago via repeat c-section. There are almost 3 years in between my first child and new baby. In addition, my 3 year old is about 40 pounds. Also, I have a spouse who leaves often for work. Lastly, I was also advised not to try getting pregnant again for at least 1 year as well. However, I knew with how busy my first kiddo was keeping me at about a year old, I wanted a larger age gap between the kids so that wasn't a problem.
I am currently in that time period with the weight restriction. Because my toddler is a bit older, he's actually been very understanding that I can't lift him due to having a "boo boo". I think if I would have had a baby before this time (let's say 2 1/2 or younger) - my toddler would not have dealt with it well. While I can't lift him up, he still cuddles me on the couch occasionally. I think not being able to do as much with my toddler during this time period has been mentally harder on me then him so I still am trying to find creative ways to engage with him.The very couple times I've driven him to daycare, he is able to climb himself into the car which helps. Once again, I don't think he would have been able to do this without my help if he was under 2 1/2. If you choose to have a baby with a smaller age gap, I would just be prepared to have additional help from loved ones to help you navigate these spaces where lifting of the kiddo is needed. We don't have any family that live near us so I personally am glad we waited about the three year gap.
Also, the one thing I am trying to manage (and think will honestly be the biggest challenge) is navigating my toddler's emotions/giving him full attention when my husband is gone. Like many other toddlers, my son is trying to learn how to manage and communicate his emotions. Temper tantrums are the hardest part. Having a new sibling has been an adjustment for him and I know it won't be easy when my husband won't be home to help me divide up attention between the kids. I full on anticipate he will be very jealous of the baby when I'm the only one home with him. It's going to be interesting trying to juggle this.
In regards to the sleep schedule - we are not on a schedule right now with our newborn since he is feeding on demand every 3-4 hours. Our toddler is on a routine. The best thing we have done is keep our toddler in daycare 5 days a week so his routine hasn't been disturbed
too much. When he's home, we have him sleeping with his Hatch sound machine so he blocks out the noise of our screaming baby. The only issue we have had is our toddler is SO excited about his little brother and constantly is trying to go in his room to say "hi" to him and wake him up
.
I'm not sure if hearing about my current experiences help at all. Please make the best decision for you and your family. Also, please continue to talk to your doctor to determine any risks as you make decisions.
Good luck on whatever you decide
