Should we move to Guernsey with a newborn and leave our families?

My husband is currently going through the interview stages for a Head Gardener position in Guernsey, and it has left us with a difficult decision to make. It could be an amazing opportunity for our family, especially as we currently live in a shitty town in the east Midlands and often feel there are limited opportunities here. However, the timing is far from ideal as we are expecting our first baby within the next couple of weeks.

We have spent a lot of time discussing the pros and cons. On one hand, it could offer career progression, a different lifestyle, and opportunities we may not get again. On the other hand, both of our families live here and this baby will be the first grandchild on both sides. The thought of moving away from that support network is understandably daunting.

My husband has even asked whether he should pull out of the interview process because he is unsure. Personally, I don't want us to make a decision we might regret years down the line. I feel there is a big difference between being offered a job and deciding it isn't right, and never giving ourselves the chance to properly explore the opportunity.

There are also family circumstances to consider. My husband has vulnerable family members, although his mum has encouraged us not to let that hold us back. While I appreciate her support, I sometimes wonder if she is viewing the situation a little too positively.

I have only told my own mum because most of my family tend to be negative about things. She doesn't seem enthusiastic about the possibility either. Whenever I mention it, she focuses on the baby and often comes across as disappointed rather than excited.

Ultimately, I feel torn between staying close to family and pursuing an opportunity that could benefit our future. I don't want fear or guilt to make the decision for us, but I also don't want to underestimate what we would be leaving behind.

We've had abit more of a chat about it tonight and We've decided its a no for us moving. Mainly because of the baby we think there's a lot of risk there if the baby was to get sick or we needed family

Getting a small baby on a airplane back and forth would be a nightmare and the town also looks like it would be boring to live on after a while
