It's bending the instructions that say do not see or visit family members who do not live with you and is probably putting yourself and them at a possible risk. It is also unfair on everyone else who is conforming to the lockdown.
My DD2 and DGS2 are living in our house so we can help her. Started this before lockdown as she is a nurse. We do not see DD1 and her family but FaceTime with them They live 30 minutes away. Very hard and DGD who is 3 doesn't understand it but the children have booked a sleepover as soon as this ends.
If everyone bent the instructions they might as well not exist.
Is it me or am I getting mixed messages
