People trying to contact me

I don’t plan on letting anyone know I’m in labour (nobody is assuming I would tell them either) and I’m also going to be turning my phone off when I get to the hospital or leaving it on just so that my husband can contact me if he’s coming separately.

My mother in particular calls me a lot (often multiple times a day if I don’t/can’t pick up). Last time I was in hospital with a scare it happened to be when she kept calling me and I couldn’t turn my phone off as my husband wanted to be kept updated. Obviously she had no idea but I found it quite distracting at the time and I didn’t really feel like calling her back and chatting that night after spending a stressful day in hospital but I also didn’t want her to be worried that somethings happened to me or guess that I’m in labour since I always return her call or pick up. I’m worried that the same thing is going to happen during labour, especially as I always call her back.

My question is does anyone have any suggestions for how to deal with people trying to get hold of you when you’re in labour or have just given birth and are not taking any calls/ready to announce the arrival. A friend of mine said they told their mother who calls very regularly that they might not be able to take as many calls or get straight back to them every time around the weeks of their due date. Perhaps I should just do that?

Thank you
