Fetal hiccups - please reassure me

[ThinkPinkStink]

Okay, I've got to that stage of pregnancy where everything is a big old worry, I really hope I'm worrying about nothing.

I'm 36+5 - for the past month or so baby has had pretty regular hiccups (usually coinciding with me eating lunch) for 2-5 minutes per go. I thought it was pretty 'cute'.

This morning I, like a fool, Googled fetal hiccups - and there are all sorts of stories about how sometimes it can indicate that the baby is trapped in its umbilical cord.

In good news I've had four dopplers in the past six weeks (most recently yesterday) and everything has been fine, nothing to worry about (baby's heart varies between 138 and 148 BPM). Movement is otherwise normal.

I'm over-worrying aren't I?

Christmas - trust me, if it happens, you'll know!
Dd hiccuped all in the womb all the time, and as a baby. Every time she laughed she got Hiccup, up until about 5yo. She rarely ever gets them now (10), laughs plenty.
Ds never hiccuped in the womb, think he's had them only once or twice on the outside. (7)

Christmas - it often starts later, you might notice around 32 weeks maybe.

It's just tiny, rhythmic little jerks :)

Thank you
