Charlysmum, :hugs: It is hard when everyone thinks they know what is right for you and your baby. Of course, it is entirely your choice as to whether you continue to bfeed Charly at night. You are right, their main source of nutrition for the first year is milk, whether breastmilk or formula.
If you have a look on the ABA website, you will come in contact with heaps of mums who never night-weaned their babies. There is nothing wrong with feeding overnight, although when they get teeth there is arguably a higher incidence of tooth decay.
On a personal level, I have decided to try to night-wean Natalie, simply because she is waking too often IMO, to be hungry. If the waking didn't bother me, I wouldn't be weaning, but I'm just so tired so that's why I'm doing it. Technically, they don't need feeding overnight if they're putting on weight... Having said that, I'm willing to continue to give ger two feeds between 7 and 7 because she seems to be much more settled with those. Perhaps we will drop those when she increases her solids.
Tressillian have a national helpline - if you want another opinion, please give them a call. I've phoned them about three times now and they have been really helpful.
Charlysmum, you are doing such a great job! Try not to feel pressured by people who think they know more about your own baby than you
