Yes it's hard in the sense of having to juggle everything more carefully such as co-ordinating nap times, getting two ready to leave the house at the same time and one decides to poop so it's all hands on deck out of buggy nappy change back into buggy etc kind of thing.
Keeping an eye on two crawlers (or one bumshuffler and a crawler in my case) is harder.
If possible having an age gap where one will be at nursery whilst the baby's at home is ideal. Remember with two you may not have one magical afternoon nap times with your baby anymore as the older one may not want or need naps at the same time, or at all. Or baby nap times were a precious opportunityt to recharge your own batteries whilst he slept.
But all the rest of it you already know so you'll breeze through the emotional and practical stuff. If your other child is old enough they'll enjoy
helping you running for wipes and nappies and so on.
Check your metabolism. I noticed after my first baby (age 38) my body shape pinged back ok quickly and I still had the same energy as before. After baby two (aged 40) everything just went to pot. Body, skin, energy, patience. It must have been a metabolism thing due to my age, I don't know. So keep your healthy eating and vitamins up!
If I had a choice I'd have stopped at one for financial, mental, logisitical reasons but gorblimey my second was a son and I have to say the cutest on the planet
