My baby slept over at her granny’s last night for the first time (my in laws). She is 19 weeks old. When I asked how the night went my MiL said during the night feed she gave baby 3/4 of the bottle in her arms and then lay her down and gave her the last 1/4 lying in the cot. Is this safe or normal? I’ve never heard of anyone doing this before? When I BF I did feed lying down but baby was sideways whereas last night she was flat on her back.
