I actually think DS2 has made the lockdown easier for everyone. He's injected some well needed chaos and cuteness into our lives.
We frequently throw a cheese toastie and a flapjack kind of dinner at DS1
- not sure why this is acceptable for toddlers but not for preteens? In fact if we are completely frazzled from baby wrangling he is perfectly capable of making himself some pasta or frozen pizza or beans on toast.
You don't need to worry about getting the older one(s) not to do things the little one can't do, because the little one seems to see the big one as some kind of weird adult-child hybrid and is perfectly able to accept that they do things that he can't do yet. Also the older one is old enough to go off and do whatever it is they want to do on their own without the little one tagging along.
You notice how all the people pointing out the negatives are the ones who haven't done it?
Okay okay, to be fair, I will try to think of some negatives....
When it gets to the end of the day when DS1 starts to get chatty, I am generally exhausted and can't give him the attention he wants. Maybe if I didn't have a breastfeeding toddler all night who wants to get up at the crack of dawn, this would not be such an issue, but I can't say for sure. I can't remember if this was also an issue before the pregnancy because that feels now so long ago now. DS1 can be quite draining as he has ADHD.
Childcare bills - yes unfortunately that one is a negative. But surely predictable and you can do your own sums about whether or not you can afford it (just check whether prices have increased!)
It's sometimes a bit weird when advice/popular products have changed and you are out of step with everyone else because you want to do it the way you did it with your older ones. On the other hand it does at least come back to the point of having the confidence of an old timer - you have the balance of the newer info from newer guidance/new products etc and the knowledge that your older ones turned out fine even though they didn't have this or that new thing, so you do feel like you can make a genuinely right choice rather than being swept up in the latest trend.
