Too early?

So I've had 3 micro preemies.

24 weeks, 24+1 weeks and 26 weeks.

My consultant and I are doing all we can to keep this little one in - I'm 16 weeks today.

Well I'm highly anticipating another micro preemie and in all honesty so is my consultant. She's hopeful for 28 weeks and I'm hopeful for viability.

So I'm planning on packing my hospital bags at 20 weeks.

My partner is saying it will be way too early and I'm cursing myself.

From previous experience I've been in hospital for over a week with my births (leading up to, trying to keep them in and recovery)

So I need a decent amount of things especially when my partner can stay with me before and after birth.

Before I have people saying "why have another baby" this darling boy wasn't planned and his vasectomy failed.
