very subtle trembling when baby feeds to sleep.

[cockle84]

Twice now my baby 51/2 months has started trembling whilst feeding (bottle). It only lasts for a few seconds and is very subtle but scary nonetheless. The two times she has done this she has been absolutely shattered and fallen asleep on the bottle so I assume it's something to do with being tired.
Anyone had a similar experience?

My 7 month old does this! She is dd3 and I don't remember it happening with the other 2 The first time she did it, my husband nearly dialled 999! She only does it the odd time and also when she falls asleep feeding.

I actually though EVERYONE did this. Both my sons AND DH go trembly just as they are falling into sleep! DSs are now 8 and 6 and Dh is 52!!!
