15 month Old, how to wean off Teat to Spout ???

[lovinit]

I made the mistake with DD2 off not doing this sooner or with more persistence and now almsot 3 she will only take her milk from a bottle and sucks at it like a dummy before falling asleep at nights ... DD1 took to her beaker at 13 months and has never looked back. DS3 is almost 15 months and I am trying to change his morning feed to the spout or beaker but he simply refuses to drink his milk whatever the beaker I use ...

Pls any tips ? Really do not want a repeat of DD2 . Also any tips for DD2 ?

Is there a problem with her having a bottle if it's only once a day and she doesn't spen the night sucking on it? I would just go with the flow - they won't be taking their bottles to University with them!

Try an open cup instead?
