Hi everyone I need some advice weather to buy a sleepyhead. my Dd (4.5 months) has always slept in a bednest but is fast becoming too big for it as is regularly giving the sides a wack in the night ( have now cushioned the sides ) we have tried several times to put her down in her cotbed but she seems to hate it!! Someone told me about the Sleepyhead yesterday and I wondered if anyone has used it for the transition into a cot before? Or is my DD too old for it now?
