DD is 18 months old. Her bedtime routine normally starts with a bath at 6pm and she is usually in her cot dropping off to sleep by 6.45pm.
Next week (on a weekday) is MIL's 60th birthday. At the weekend we received a text from DP's sister saying she was organising a meal at a pub not too far away (about 15 min drive) for her birthday and could we make it. She'll be booking a table for 7pm.
Am I wrong in thinking that by the time we all get there (DP's brother and family aren't the most punctual), order food, eat, have dessert, coffee etc it'll be 9.30 at the earliest by the time we leave? Meaning DD won't be down to sleep until at least 10pm.
I said to DP that DD and I wouldn't go (we've missed birthday meals for the same reason before recently) but once we replied saying it would just be DP going we then received messages asking why we couldn't keep her up a bit longer for once, it won't hurt her etc. I know I'm quite precious about keeping to her routine, but she thrives on it and generally is a good sleeper because of it.
We will be going round to see MIL on her birthday after I finish work, and will stay until they leave for the meal (so a little bit past her bedtime anyway) but I know that if I try to keep her up until 10 she'll be grouchy and grumpy and nobody wants to be eating at a pub with a grizzly child. I'll also be the one to bear the brunt of it during the night if she can't sleep properly. Plus I have to get her up at her usual time the next morning for nursery, so it's not like she'll have a chance to catch up with a lie in.
So, AIBU or not?
