Preface this by saying, I know I'm incredibly lucky.
We have one baby, 4mo. He has been a very easy baby from birth, who sleeps and feeds well and is a happy chappy most of the time. DP is a very equal parent, we alternate being 'on duty' overnight, he does every nappy because I breastfeed, we split awake time with baby if we're not all together so we each get time to ourselves to do stuff we want, and he will be taking 6 months off work parental leave when I go back when baby hits 6mo. We've got lots of supportive family. I found weeks 6-12ish very hard when my partner was working, just a bit relentless, but now ds is a bit more interactive I'm enjoying him again.
We are both from large families- I have 4 siblings and DP has 3. We always envisaged a big family with lots of kids. We're not rich, but we earn well and if we are careful with money could afford this (so probably not expensive foreign holidays and bedrooms would be shared, but we grew up camping and sharing rooms and are happy with that).
Now our baby is here, I'm torn about whether to have another. We try not to be all pfb, but I know we won't be able to give a second, third etc the same attention ds now gets, I worry we won't cope if the next baby is a terrible sleeper, and I don't want to spoil the great set up we have. But also we love our siblings and I kind of want that joy for him. How did you decide on how many to have, and what would you advise?
