I have two DC, DC1 is 5 & DC2 is 3. Everyone said when DC2 came along they would just slot in, but it didn't happen that way, right from the early days our older child was far more accommodating and DC2 has never really gained cooperation skills despite my best efforts to keep things fair since the early days.
DC2 is very possessive of me and throws a fit whenever DC1 is holding my hand, having a cuddle, sitting on my lap etc. Either getting very emotional/screechy or aggressive and violent against DC1. I don't give in, but instead explain (sometimes calmly but recently with increasing frustration and exasperation) that everyone deserves a turn. Often DC1 will make space so they can both have a hand or both have a knee etc but even this isn't enough, DC2 genuinely doesn't even want me touching or looking at anyone else. Sometimes DH takes DC2 away from the situation until calm, but he's not always around. I thought it would get better as language skills improved etc but so far it just seems they are more efficient at expressing the wish that DC1 gets off 'MY mummy!'
It's really affecting my relationship with DC1 who I feel now often goes to DH when they need something to avoid a show down with the smallest. This in turn is making me very resentful towards DC2 as I don't like being in the centre of this tug of war. I have two hands, two knees, there should be space for both!
Any tips on how to combat it? Someone suggested a corner or step or something for DC2 to sit on and have a moment, but I'd assume I'd be needed to ensure that is carried out which means my attention would be firmly away from DC1 which kinda feels like DC2's goal! We've been waiting for this 'phase' to pass but seriously 3.5 years on I feel I'm missing out on DC1. I don't want this time to pass to find they've outgrown even wanting to hold my hand anymore just because the little one is constantly throwing a wobbler!
