I'm new to mumsnet and I certainly don't ever write on forums, but I feel I need to reach out to other women who are in a similar position to me. I have been married to my husband for nearly three years now. He has 4 children from a previous marriage (19,17,15 and 14 years old). One older lad and the rest girls. I always knew he had kids and being a step mum never worried me. We fell pregnant with our own little boy and he is now 16 months old. I found out I am pregnant again (this wasn't planned) 6 months ago. We are having a little girl and I am very happy about it. A few months back my husband's ex wife abandoned the kids. We had to take immediate custody of the two younger ones and they came to live with us full time. It's been a hard time because I have been trying to adjust to being a new mum and then being a full time step mum to someone else's children. most of the time I'm okay, but in the last few weeks my husband's two older children have come to live with us too. all 7 of us are squashed into a 3 bed house and the workload has tripled resulting in less time that I spend with my 16 month old. Of late I have been becoming jealous and frustrated that at the moment I can't spend as much time with my son. I'm d tired more because of being pregnant. I don't like the way my step children play with my son. They often grab him, hold him, toss him around and I guess my instinct tells me that he just wants to play, explore and runaround, but often he can be doing this and they will stop him. He then gets frustrated. Tonight I cracked because my youngest step daughter grabbed him, he flung his head back and wacked it hard on the floor. I shouted saying no more grabbing, throwing around etc. of course I felt guilty then, but I also feel he's my son and I am the one who has control of what should and shouldn't happen. I am also finding disciplining my son hard too, because everyone wants to do it. Most of the time I am pretty chilled and let things go. I know it's not forever but recently I have been thinking I don't know how I am going to cope with a newborn, my toddler and everything else going on. We need to move but that's not going to happen any time soon. I often think about moving out and staying in the relationship, but that won't work. I have accepted what's going on, and I know that the kids need female guidance in their lives and I love that I can give that to them, but sometimes I feel so overwhelmed with what's going on that I just need to confide in other people who are step parents too, as it really is a hard job, being a parent is hard enough but then having to look after someone else's kids too, omg!!! Anyway, I love all the kids and I've always said that what's important is they have a good start in their life, but any advice you have on how to deal with them and their relationship with my own children would be great. Thanks for listening xxx
