For context, my daughter and her partner have lived together for 15 years and we have NEVER just turned up at their home without an invitation. Their first baby was born in February, so we saw him up to five weeks and now he is five months. Last week the big day arrived when we could go for cuddles! I realise now that the day was chosen because partner was out at work for part of the day (mostly WFH)
We arrived at 1:15, taking lunch. Baby was napping so we ate lunch and had a lovely catch up with our daughter. SIL arrived home about 2, coinciding with baby waking. My daughter invited me to go with her to his nursery and I gave him his bottle, then had a play. SIL had gone to finish some work connected with his morning appointment, came down at 3:15 and said 'are you still here - you may as well move in. ' I have felt upset since and I know he would claim to be joking but it just didn't come over that way.
So - would you mention it, just arrange to visit if he is out, carry on as normal? My daughter has already invited me to call over this weekend as she knows my husband is at work, but I have feigned busyness. WWYD?
