I’ve got a newborn and a toddling sprinting biting nipping 1 year old and a 31year old.
If the one year old stops biting and the mmr stops making him into a tiny bear of a person he might be easier than the adult
.. but at the moment he’s winning.
The newborns only hard points are lack of help, like i can’t take him a walk in the buggy (1 year olds mmr fever but must obey the rules and stay in) can’t take him to visit relatives who’d cuddle him for hours while I lay on the floor like a lump after the all night boob buffet. Other than that he’s a newborn, feed it, burp it and never sleep again 
1 year old isn’t talking or listening yet so he just runs at you launches a cup at your head and bites you like some mad rioter, I can’t speak to anyone on the phone if he can hear them because he thinks they’re here so throws a full blown hour long scream fest, he obviously can’t burn enough energy off either.. I don’t think he could outside either but maybe the mental side of baby group would help, or atleast maybe help him speak (if you know what bbbff is let me know).
The adult.. Jesus, we need something every 15 minutes, he must do things, he can’t leave the toddler incase he falls, he could be doing xyz but it’s shut.. the only thing that isn’t shuts his mouth
. Fortunately he still can’t work from home so he’s effectively got 8 hours of day care.
