Well that almost says it all - have posted before about weight gain concerns and when DS3 was weighed this week he is down to the 25th centile (and was a big boy at birth) and has been putting on weight very slowly. He's 9 weeks now btw.
Decided to give HV advice a go and top up - for last 2 nights have given a carton of formula, half at 7ish and half at 11ish.
He still bf before and between and after the second bottle before going to sleep. He also gets through this 100ml in about 3 minutes whereas he will bf slowly (and sleepily) forever.
Head tells me this is the right thing to try, but emotionally I'm a bit all over the place about this and just need a bit of handholding I think (not criticism please ). I intend to carry on bf apart from these top ups and have done some mixed feeding with DS2, but didn't start that so early which is perhaps why I feel bad about it this time.
