My partner and I split whilst I was pregnant with our third child. Prior to the baby being born, our 2 year old twins had been spending weekends and his house. Now we have a newborn, I'm breastfeeding so I'm not comfortable sending the newborn for overnights, but I'm wondering if I should still send the twins for overnights or not to split the children up. Has anyone else been in this situation, do I wait until the newborn is older and send all children together or is there no harm in sending the twins on their own without their other sibling?
