When do you start monitoring babys movement?

[Numbthumbs]

This is my 2nd pregnancy and i felt baby move really early on, about 11 weeks. Im 16 weeks now and there is no regular pattern to its movements, but i do feel it every day. Just wondering when i start having to actually think 'ooh, i havent felt it yet today?' (forgot to ask midwife)

Thanks

Think it's around 28 weeks although if you start having regular movements before then and they change probably best to call MW.

Thanks, a good while yet then x
