i hate all of this "it's not your baby so you shouldn't care" attitude. thank god there are people who are concerned for other people's children.
there is no reason to ever feed a rusk to a baby at 9 weeks. god forbid if the baby were to choke and die would people just say "oh well, it was her choice to feed the baby a rusk"? the woman is clearly uneducated in infant nutrition and could do with a push in the right direction. can't see anyone making an INFORMED decision to feed their baby something like that at 9 weeks, and putting it in a bottle... pfft.
If the OP was concerned then she would have said something to the mother of the baby in a friendly way. Instead she has come on a forum to get a response and what seems to be ridicule another mother, not only about feeding her LO rusks but also about taking them for immunisations whilst she has a cold. Now if she actually cared in a nice manner she would try and help the mother in another way than posting about it on a public forum. My opinion.
there are certainly things that the OP can say to the mother, i agree. but i don't think her intention was to "ridicule" the anonymous mother, more just to express her concern that she is making the wrong choices with her child and to receive opinions on whether people agree. having a rant is often the first port of call, you rant, you get other people's opinions and then if they agree with you and cannot offer an alternative explanation for why something has been done then you conclude that it must have been a mistake and you can therefore talk to her about it. it's much better in my opinion to do it that way than to go straight to someone and say "you shouldn't be doing this". it's not like OP has discussed this with people that the mother knows, the woman remains anonymous to us all, so she isn't embarrassing her in any way.
and for the record i haven't seen anyone give any reasonable explanations for why the mother might be doing this for the best. all i've seen is people saying "no she shouldn't be doing it, but it's none of your business" which to me isn't good at all.
i don't know why people think it's best to turn a blind eye to a child's welfare.
where does that end? at what point should you intervene?
