I’d say hell no.
but I’d also be asking some very tough questions.
how long does your son anticipate this could last for? My DC is a teen and still doesn’t sleep properly and I’m still woken in the night. DC has sen.
is he exaggerating all he does and the level of His child’s wakefulness? Some people are arseholes if they’re woken up only once and are totally unreasonable about it. If this is the case, he needs to grow the fuck up, get over himself because there’s 18years ahead of restless nights with constantly changing reasons why.
is the baby above normal with regards to the crying/neediness/colicky etc?if so then yes they need help and support not split up for most of the week, that’s not going to work.
if yes to a above normal needy baby, how does he expect his GF to function on the limited sleep as well? Is she functioning? I bet she’d be zombie like and agree to anything because she’s not got the mental capacity to deal with it.
could he hire in help for some of those chores like general cleaning?
is he just pissed he gets no free time now and it’s not about sleep but being able to not do much after work?
does he realise that him moving out part time is effectively splitting up his family and the important bonding for him with his Gf with the baby won’t happen?
does he understand that caring for a baby isn’t a transaction right? That he doesn’t get GOOD sleep and check out if 5/7 days of family life because he claims he does more than his fair share. Caring for children is a burden to mum and dad that you can’t check out of.
is he really doing this for sleep or could they be planing this for benefit fraud? Not an accusation, cost of living is immense everyone struggling, having a baby is expensive as hell will do what they can to survive and I know a minority of couples that do this via desperation. Is there ways you could help with budgeting and support, not giving money you don’t have?
