Overthinking DKA

Hello, I don't have an advice you might want to hear, but my advice is given you have no family nearby, your health plus a newborn, I would really really advise that your husband works less. I understand 100% money strain (I am sahm and no we aren't well off, my daughter got t1d so I have to look after her since she is under 2) but being your husband I would have been constantly worried about you and my child. So this is something to consider.
Another advice from a mum who been there, yes it is really hard when baby is so small, but trust me, it DOES get easier when they grow and are more independent. Every child is different, but don't let anyone scare you saying it's easy now and when they crawl and walk it is full on. Not my experience. It was insanely intense until baby girl started to walk 🫶🏽 It got so much easier.
Re your diabetes plan, maybe just pre plan meals? So u don't have to think about it on the day? I ratio her meals so I don't count much either.

A CGM might be worth looking into. It doesn't read ketones, but would alert you to highs and lows of your blood sugars.
I use a dexcom along with a YPSO pump, and the pump will automatically give me more or less insulin based on the blood sugar reading every 5 minutes. But there are different CGM and pumps out there, The YPSO pump is one of the better ones during pregnancy apparently (my diabetic nurse says) and thats what was available and given to me at the time. I can't comment on other pumps
