Hi, so my little one will be one at the end of the week. My partners daughter from a previous relationship is 10 (who lives with her mum about an hour away) has met our son a handful of times, she’s been invited to come to our house literally hundreds of times since he was born, we’ve offered to go to her , go on days out etc etc. On the occasions she has been around him she’s never really shown any interest. It may be jealousy but we’ve tried our hardest to overcome this and tried to include her as much as possible. When she’s around the baby she seems annoyed by him, doesn’t interact with him, takes his toys he’s playing with and is so rough I find myself hovering around them all times. She will do anything she can to divert our (especially her dads) attention away from the baby, demanding that she wants to do this and that , knowing it’s not possible with baby in tow. Even before the baby came along my partner regularly was almost at the point of tears as she’d gone from coming here every weekend to not wanting to hardly ever, saying she couldn’t be bothered or saying she’s only come if I.e we’d take her horse riding or buy her loads of clothes etc. Since lockdown she’s been a couple of times, openly admitting she’s coming because she’s so bored at home . The last time I woke in the night to find her purposefully poking the baby to wake him up, having been told he’d just started sleeping through the night and I was working a long day so up at 5 the next day. Anyway I digress.... so my partner rang her a few days ago and happened to mention it was baby’s birthday soon, to which she didn’t react. Last night he was on the phone to his dad and I overheard him saying he is going to pick her up the day before his birthday so she can spend the day and weekend here. I’m more annoyed at the fact he didn’t even think to discuss this with me. His thought is she has the right to spend the day with him on his birthday, my thinking is that she’s not that bothered. I’m dreading the thought of my sons first birthday being ruined by her demands and behaviour. She has a baby brother at home with mum and she’s fine with him . Obviously we can’t have a party due to lockdown but we’ve asked close friends and family to obviously socially distancing to come and bring his gifts etc so at least they can see him, if from a distance ie outside the garden. I don’t know what to do. I don’t want to seem like the evil step mum but I want my baby’s birthday to be about him, not a girl who quite frankly has no interest in him and I just know she’ll do everything she can to ensure he doesn’t get the attention he should have on his special day
