I should think so, if he seems to be drinking til he wants to stop. That's what I'd be giving a very new 'pet' lamb if I had to bottle feed. Hopefully he'll be allowed to feed on his own soon.
I lost Daisy when her kids were about 10 days old. I had Daisy's mum Ellie, who hadn't kidded that year but who I'd milked through. When Daisy died I tried the kids on Ellie because they were seriously unimpressed with a bottle, having had the real thing. No way, Ellie did
not like them and was having nothing to do with them. Well I carried on tying her up but she made such a fuss, kicking and jumping, I didn't think they were getting much, so I bottle fed too.
On about day 3 of this, as I'd just finished with one squirming kid (whose full name is Rowan Wrigglepants, from this experience! ) I turned round to look for her brother as he wasn't hovering nearby as usual. And he was feeding from Ellie

I let go of Rowan, who ran up and suckled too - and that was it, Ellie raised them from then on
So it can take a day or so but given that this little one is hers too, and she's calming down, I think it looks like she'll take him back.
