I think there are three main factors that influence recovery/getting to a new normal
1-birth
2-baby (health and development)
3-age
1- birth
I'm an extreme example of slow recovery. I was seriously injured during birth and I went through a rehabilitation process (forceps, forceps, forceps... Please check the risks associated with instruments/operative delivery). Too long a story but I'll give a few milestones.
3 months Can walk further than 1/2 a mile
7 months Excruciating coccyx pain finally starts to receed which means I can sit a bit better
15 months Can drive again! (with a cushion)
18 months Surgery to remove scar tissue
Back to your question, I think I felt more normal when I could drive again. The feeling of being trapped in my own body (and pain) slowly lifted.
Generally I think weight loss plays a big part too. Still half a stone too heavy but getting there
Most women I know got back to their prebirth weight between 6 and 12 months. Only personally know of one freak example of a mum back in her jeans at 8 weeks!
2-baby
My baby was physically healthy and slept well. I imagine things are much more difficult if your baby has special needs after birth. I personally know of two mums whose babies had severe reflux and I can say they were sleep deprived for 1 whole year. I know of another mum whose baby had jaundice for months. For 4/5 months, she was constantly going to see doctors.
After the initial 3 months, luckily my baby slept through. I still felt exhausted but not permanently jet lagged anymore.
A newborn schedule is gruelling and I found weaning a little stressful so the best times in my baby's development were between 3 and 6 months and between 8 and 10/11 months. After that I have found it really hard. Spending the day with a whining child hanging off my leg the whole day is not fun. We increased from 2 to 3 days at nursery at 12 months (we started 2 days at nursery at 6 months because of my injuries/amount of medical appointments I had). Things have improved since my child turned 18 months. I feel I can breath again.
3 age
Let's not kid anyone. You have tons more energy in your mid twenties than you do in your late thirties! Your age will definitely influence your physical recovery and how tired you feel later on.
20 months on I don't have time for hobbies. I hire a babysitter to go to the cinema or go for a meal with hubby. I find that all the house stuff takes up any free time (laundry, cooking, dealing with general house maintenance, planning short trips and holidays, keep in touch with friends). When I get a minute I usually have a nap!
I don't think your question is silly. All the best!
