My DD is 5 and desperate for a sibling. I’m now 6 weeks, which is a bit of a miracle as we’d been trying for 3 years, were told we were unlikely to conceive naturally, and had pretty much settled on adoption. I have a scan in a couple of days to check everything is in the right place and I don’t know whether to tell her then, if all is well, or wait until 12 weeks. Close family and a few friends know because I have fairly bad morning sickness, which if last time is anything to go by will only get worse. Would it be silly to tell her next week? I’m worried she’ll not understand why Mummy is so ill and also worried that someone else (ie MIL or SIL!) will accidentally let slip before we can tell her.
