I think I need some advice/reassurance mumsnet style ass - kicking.
I try and be brief but don't want to leave out anything relevant.
I have 5DC, 4 aged 13 -6 with stbxh and 10 month old with DP.
We've decided no more DC and DP even wants the snip. Although money is a factor, even if we came up with the euromillions, other things such as giving all the DC enough attention, health (pregnancy and labour were both a tad tough) and actually having time together as we currently work opposite each other to reduce childcare needs etc all mean we think it is best to stop at 5.
Youngest is DP's only biological child but he is a fantastic stepfather /role model, older DC adore him and he treats them very much as his own. My concern is that there is a 5 year gap between the youngest two and that when DD grows up she will feel left out /lonely. Her old siblings dote on her but I only had two year gaps between the others and they are (for now) very close. Am I being ridiculous? I think I am but it's a real nagging doubt in my mind. There's a child who is permanently knocking for my DS's to play as he only has much older (late teens and twenties) siblings, no problem and he is always welcome but it feeds my doubts about DD and not giving her a sibling closer in age. I guess in a long winded way (apologies and 
on me) I'm asking for people who have had bigger gaps and those who have had children with new DP if they feel their younger children have felt left out or lonely.
