almost 4yo wetting his bed after birth of his sister 7 weeks ago

[Hpbp]

good morning all,
I need your advice on how to proceed with my eldest son who is almost 4 and wetting again his bed every night for the past 5 days. He has been dry during day time since he was 3 and night time for 5 months with the odd bed wetting once a week or every 10 days, but ususally he could spend all night without waking up for a wee or he would come to me to ask to go to the toilet and went back straight to sleep.
I had a second baby 7 weeks ago, he seems to like her, giving spontaneous cuddles and kisses, letting me know when she cried even though he would ask me for food if he saw her feeding... He was still dry until last week, when he started weeing every single night. I reassured him the first time, got upset a little bit the second night, explained to him that I needed his help to look after him and me and his sister, on the fourth night I got very angry. But still, he keeps on.
I don't know what I should do : put him back in nappy at night ? or insist with the drawback of washing bedsheets everyday and being waken up in the middle of the night whilst BF the younger one ?
Thank you for sharing your experience with me

Hi I had the same thing with my four year old dd. baby is 12 weeks now and it has stopped. She was very loving with baby dd during the day but wet the bed at night. Easy to say but try not to get angry. We just woke her to go to the loo when we were going to bed. That seems to have worked. Plenty of hugs and kisses and reassurance that you still love him during the day.

My son had a bid of regression when my DD was born. He was great with her but it is a big change having a whole new member of the family!

I think I did put him in training pants at night and explained that I understood it was tricky to hold it etc and that I was sure he'd remember how to so it again soon. Then I ignored it totally and he started improving on his own and wanted to tell me about how he had remembered! I gave him lots of praise and it just kept getting better.

I'm sure some people would say that this is a step back and you shouldn't go back to nappies but I didn't have the time or energy to keep washing! Good luck.

Take heart, it will not last I'm sure. I think it's probably quite normal for a young child to want unconsciously the attention he or she sees a new baby getting at nappy change time. When DS3 was born last year DD2, then 4.9 and the youngest up till then, started wetting her pants again although she had been dry for 2 years in the day before that. I thought it was probably significant that it was only at at home and only when I was feeding or changing DS3. (She was still wet at night anyway so we could not have seen any difference then caused by her younger brother.) I agree with other people - it is best treated as just accidental with emphasis, at other times, on all the things she can do which a baby cannot; especially the things she can do with Mummy and Daddy. In addition though I did tell her she would always be one of my special babies llke all of them, however big they were and I would always be her Mummy. The wet pants got gradually better after four or five weeks. I'm sure it was not deliberate - she seemed quite upset.
