Bit of background. DH and I have a 10 month old baby. I returned to work, on reduced hours, two weeks ago, I work around 30 hours a week. DH works 40, over 4 days, so 10 hour shifts. He leaves early in morning after walking dog and returns just before dinner time, when he walks dog again. Baby currently sleeps in bed with us, which I find much easier for feeding him through the night.
My day consists of waking with baby, getting him changed and breakfast, taking him to daycare 3 times a week, working from home, collecting from daycare and giving him a dinner and usually bath before DH gets home. I then make us dinner and get baby to sleep, although DH will make dinner after walking the dog if it has been a tough day. We both have a weekday off work to look after DS and we have weekends off. Apart from night feeding DS and taking him to and from daycare, which I do, we tend to share all other child care, although I have had to occasionally encourage DH to play with baby a bit more instead of plonking him in front of TV. DH is very good with DS, who adores him, we share feeding him meals, nappy changes, bath times pretty evenly.
Twice a week, I go to my hobby, once on a week night and once on a weekend morning. Last night once DH was home, i left DS with him after giving him dinner, but before bath time. Plan was DH would take baby and dog for walk and then come home for bath before making himself some dinner.
I messaged shortly after leaving asking how walk had gone, as I thought DS looked very sleepy as I was leaving. I told DH baby would probably go to sleep straight after bath. DH said it was fine, he had been bathed but didn't seem sleepy so was playing. When I came home, around two hours later, DS was still awake. This isn't unheard of, but I was a bit surprised. I fed him myself and managed to get him to sleep within minutes, he was very tired. I didn't really think too much of it.
When I was getting ready for bed, I noticed none of DS's bath things had been moved, sponges were dry, toothbrush dry etc. I asked DH why that was if he had been bathed. All DH said was that he had forgotten to brush his teeth, but he had definitely had a bath. I wasn't sure, but wanted to give him benefit of the doubt.
This morning as I went to change DS before DH left for work, I noticed that DD had blue fuzz in between his toes, which was from the socks he was wearing yesterday through the day. I called DH and pointed out I knew baby hadn't been bathed, as he had fuzzy toes. Dh admitted he had lied about bathing him, to which I said I was upset that he felt he had to lie to me. He didn't give any reason for why he didn't do it, just said he was sorry and that he wouldn't lie again. He had to go to work, so I left it at that.
AIBU to be upset about the lie? I wouldn't have been overly concerned if baby hadn't had bath, I might just have washed him this morning before daycare if I thought he needed it, we have done that before. He probably would have gone to sleep earlier if he had had his bath, it is part of his night time routine, but if DH had been too tired or too busy to do it, it wouldn't have been the end of the world. But I am upset that he would lie to me about something concerning caring for our child? And it makes me worry that in the future I will worry about him saying he had done things whrn he hasn't?
Sorry about the long spiel, just looking to get some opinions over this.
