Absolutely sleep deprived mum of 2. DS 6 months and DD 3 years. DD behaviour has changed so much since the beginning of lockdown and I appreciate and accomadate for the confusion and upset lockdown has caused her aswell as having a new baby brother. But she is just constantly screaming,demanding,hitting,biting and shouting. I can't turn my back for a second as she shoves food and toys in the baby's mouth. I've had a talk with her about how its dangerous and only mummy is allowed to feed him but she's my helper etc. She snatches and hits the baby but at the same time absolutely adores him. I try and take her out as much as I can (tier 2) and do activities when we are home but it lasts minutes before she destroys it and then runs off to pull apart the house. I have to take the baby with me all round the house because she's so quick and almost calculated and does something dangerous which doesn't help with his clinginess with me. I can't remember the last time I got even 4 hours sleep let alone a whole night and what even is time to myself. I barely have time to go to the loo let alone wash my hair. My husband comes home after work in the evenings and he's helpful but by that point I'm exhausted and all touched out and just feel like a zombie. He's so supportive but I feel like it's taking a toll on our marriage as we never get time to ourselves. Please tell me I'm not the only one and I'm not the shittest mum in the world?!
