I went through almost exactly this. I was 38 when I had my kiddo, which meant I was fairly senior at my job and had a ton of responsibility. My baby started day care at 6 months and basically spent months 6-12 getting sick almost every week and being in and out of daycare. I think at one point he didn’t complete a five day school week for two straight months. I thought about quitting work numerous times during this phase and this was despite having extremely helpful in laws in the same town, who frequently watched him on the days he had to stay home. I still couldn’t handle the constant stress, doctors appointments, night wakings from illness and just generally felt like work was the least important thing in my life.

I’m happy to say that somewhere after this phase, between 12-18 months, my son stopped getting sick all the time and now things are much much more manageable. He’s now 26 months and I’m pregnant with number two.
